Desc	MUSEUM & PUBLIC PROGRAMS:IN 2020, THE MUSEUM LAUNCHED THE PHYSICAL EXHIBITION "K-9 COURAGE" THAT HIGHLIGHTS THE DOGS WHO SERVED DURING THE RESCUE AND RECOVERY EFFORTS FOLLOWING THE 9/11 ATTACKS, AS WELL AS TWO DIGITAL EXHIBITIONS: ONE FOCUSED ON THE PRE-9/11 HISTORY OF THE WORLD TRADE CENTER AND THE SECOND EXAMINING THE INTELLIGENCE AND MILITARY OPERATIONS THAT LED TO THE KILLING OF OSAMA BIN LADEN NEARLY A DECADE AFTER 9/11. TWO NEW AUDIO TOURS WERE ALSO DEVELOPED AND RELEASED: ONE FOR THE OUTDOOR MEMORIAL PLAZA FEATURING A 45-MINUTE TOUR ABOUT 9/11, THE VICTIMS OF THE ATTACKS, AND THE DESIGN OF THE MEMORIAL; AND A SPECIAL TOUR ACCOMPANYING THE PHYSICAL EXHIBITION "K-9 COURAGE".FOR THE 19TH ANNIVERSARY OF THE 9/11 ATTACKS, THE MUSEUM AGAIN PRODUCED THE "TRIBUTE IN LIGHT", THE ICONIC ANNUAL MEMORIAL THAT DOMINATES THE LOWER MANHATTAN SKYLINE FROM DUSK ON SEPTEMBER 11 TO DAWN ON SEPTEMBER 12. THE YEAR 2020 MARKED THE MUSEUM'S SIXTH YEAR OF OPERATION, DESPITE THE CHALLENGE OF A GOVERNMENT MANDATED CLOSURE. IN ADDITION TO SERVING VISITORS THROUGH ITS CORE EXHIBITIONS, THE MUSEUM PRESENTED PUBLIC PROGRAMS, AND MAINTAINED CONTINUAL OBJECT AND EXHIBITION ROTATIONS, WHICH WERE NECESSARY DUE TO CONSERVATION REQUIREMENTS AND LOAN EXPIRATIONS. OBJECTS AND EXHIBITION ROTATIONS ALSO PROVIDED THE OPPORTUNITY TO FEATURE MORE OF THE PERMANENT COLLECTION. WE HOSTED VIRTUAL MUSEUM TOURS FOR THE MILITARY AND VETERAN COMMUNITY ON VETERANS DAY.PUBLIC PROGRAMS AND EDUCATIONAL OFFERINGS WERE GREATLY IMPACTED BY THE PANDEMIC, AS PROGRAMMING WAS SUSPENDED FOR A TIME BEFORE BEING MOVED ONLINE. APPROXIMATELY 20,000 INDIVIDUALS TOOK PART IN OUR ONSITE AND VIRTUAL TOURS OF THE MEMORIAL AND MUSEUM IN 2020. WEEKLY YOUTH AND FAMILY PROGRAMS SERVED OVER 500 PARTICIPANTS IN 14 PROGRAMS BEFORE BEING SUSPENDED IN MARCH. DURING THE COURSE OF THE YEAR, OVER 3,200 STUDENTS TOOK PART IN OUR ONSITE AND VIRTUAL SCHOOL PROGRAMS. NEARLY 300 TEACHERS TOOK PART IN OUR VIRTUAL PROFESSIONAL DEVELOPMENT WORKSHOPS AND EVENTS. OVER 344,000 STUDENTS, FROM ALL 50 STATES AND AROUND THE WORLD, PARTICIPATED IN OUR ANNUAL ANNIVERSARY IN THE SCHOOLS WEBINAR WHICH CONTINUES TO SERVE AS ONE OF OUR SIGNATURE ANNUAL PROGRAMS. OUR PUBLIC PROGRAMS, WHICH ARE FOCUSED PRINCIPALLY ON DEEPENING UNDERSTANDING OF 9/11'S CONNECTION TO CURRENT EVENTS AND THE ATTACKS' ONGOING CULTURAL IMPACT, MOVED ONLINE AS WELL IN THE LATE SPRING. IN TOTAL, OVER 3,200 PARTICIPANTS TOOK PART IN 2020. THE 9/11 MEMORIAL & MUSEUM CONTINUED ITS PROFESSIONAL TRAINING PROGRAMS, WHICH PROVIDE AN IN-DEPTH EXPLORATION OF 9/11 FOR OFFICERS AND AGENTS FROM LAW ENFORCEMENT, INTELLIGENCE, AND MILITARY GROUPS AND SERVE TO HIGHLIGHT THE SPECIAL CONNECTIONS BETWEEN 9/11 AND THEIR PROFESSIONAL AFFILIATIONS. EACH PROGRAM IS GEARED TOWARD MEETING THE UNIQUE NEEDS AND INTERESTS OF THE AGENCY IN ATTENDANCE. IN 2020, THIS PROGRAM SERVED 1,355 INDIVIDUAL PARTICIPANTS.SUPPORTING THE PUBLIC-FACING ACTIVITIES OF THE MUSEUM WERE ONGOING EFFORTS TO BUILD, PRESERVE, CATALOGUE, AND MAKE ACCESSIBLE ARTIFACTS FROM THE PERMANENT COLLECTION, THEREBY ENHANCING PUBLIC UNDERSTANDING OF THE 9/11 ATTACKS AND THEIR ONGOING CONSEQUENCES. THROUGH DONATIONS, STRATEGIC PURCHASES, AND INTERVIEWS CONDUCTED BY THE MUSEUM'S ORAL HISTORIANS, THE MUSEUM CONTINUED ACTIVE GROWTH OF ITS PERMANENT COLLECTION WITH NEW OBJECTS, DOCUMENTS, AND ORAL TESTIMONIES. (THE ADVENT OF THE COVID-19 PANDEMIC REQUIRED TEMPORARY SUSPENSION OF THE LATTER IN-PERSON RECORDING PROGRAM, HOWEVER.) BY THE END OF 2020, THE MUSEUM'S ACQUISITIONS NUMBERED MORE THAN 21,100 THREE-DIMENSIONAL OBJECTS, 45,400 PRINT AND DIGITAL IMAGES, 360 MOVING IMAGES, AND 3,700 ORAL HISTORIES. NOTABLE ACQUISITIONS IN 2020 INCLUDED: 312 DIGITAL PHOTOGRAPHS OF THE 9/11 RESPONSE EFFORTS FROM THE U.S. DEPARTMENT OF JUSTICE, BUREAU OF ALCOHOL, TOBACCO, FIREARMS, AND EXPLOSIVES; A MOTORIZED WHEELCHAIR USED BY RAY PFEIFER, RETIRED FDNY RESPONDER AND CONGRESSIONAL HEALTH CARE ACTIVIST, UNDERSCORING THE DIRE HEALTH EFFECTS ISSUES SUFFERED BY 9/11 RESCUE AND RECOVERY WORKERS; AND 121 HIGH RESOLUTION DIGITAL PORTRAIT IMAGES COMPRISING AN ARCHIVE OF PEOPLE DEPICTED IN JOE MCNALLY'S 2001 "FACES OF GROUND ZERO" COLLECTION. ONE NOTABLE OUTGOING LOAN IN 2020 WAS THE PRESENTATION AT HISTORIC GRACIE MANSION OF COLLAGES CREATED IN LATE 2001 BY STUDENTS FROM THE CALHOUN SCHOOL IN NEW YORK CITY AND DRAWINGS OF VOLUNTEERS AND EVERYDAY CITIZENS INVOLVED IN THE AFTERMATH RESPONSE EFFORTS BY CANADIAN ARTIST JOHN COBURN. MOUNTED IN THE OFFICIAL RESIDENCE OF THE MAYOR OF NEW YORK CITY, THE EXHIBITION "CATALYST: ART AND SOCIAL CHANGE" FEATURED APPROXIMATELY 40 WORKS EXPLORING HOW CONTEMPORARY ARTISTS CREATIVELY INTERROGATE THE POSSIBILITIES FOR EQUALITY, EQUITY, AND FREEDOM ACROSS RACE, CLASS, AND GENDER LINES. ALSO IN 2020, COLLECTIONS STAFF COLLABORATED WITH OVER 10 COLLECTING INSTITUTIONS TO PLAN OUTGOING LOANS FOR EXHIBITIONS RELATED TO THE 20TH ANNIVERSARY OF 9/11. FOUR INCOMING LOANS WERE NEGOTIATED AND SECURED FROM INDIVIDUALS AND COLLECTING INSTITUTIONS FOR ROTATION INTO THE MUSEUM'S CORE AND TEMPORARY DISPLAYS. IN 2020, APPROXIMATELY 400 OBJECTS WERE ADDED TO "INSIDE THE COLLECTION", THE MUSEUM'S ONLINE COLLECTIONS CATALOG. FIVE NEW FEATURE GALLERIES WERE CREATED, HIGHLIGHTING OUR K-9 COURAGE EXHIBITION, WORLD TRADE CENTER SOUVENIRS, AND THE RAGSDALE EEPHEMERA COLLECTION. WE ALSO LAUNCHED FRONTLINE RESPONDERS AND FACES OF GROUND ZERO GALLERIES IN RESPONSE TO THE COVID-19 PANDEMIC. INSIDE THE COLLECTION HAS BEEN FUNCTIONING WELL AS A RESEARCH TOOL, PROVIDING A VALUABLE RESOURCE FOR PERSONNEL ACROSS DEPARTMENTS, STAFF AT OTHER MUSEUMS, STUDENTS, SCHOLARS, AND EDUCATORS. APPROXIMATELY 17 EXTERNAL RESEARCH QUERIES WERE FIELDED THROUGH THE SITE IN 2020.	Desc

ANNUAL ROTATIONS OF COLLECTION OBJECTS ARE REGULARLY SCHEDULED FOR VARIOUS INSTALLATIONS THROUGHOUT THE MUSEUM. SCHOLARLY RESEARCH (II) THE MUSEUM WELCOMES RESEARCHERS BY APPOINTMENT AND FACILITATED APPROXIMATELY 17 SUBSTANTIVE, EXTERNAL RESEARCH REQUESTS VIA ITS ONLINE CATALOGUE IN 2020 AS WELL AS ACCOMMODATING ADDITIONAL REMOTE ACCESS REQUESTS BY SCHOLARS AND DOCUMENTARY FILM PRODUCERS REQUESTING ACCESS TO THESE RESOURCES UNDER THE SUPERVISION OF COLLECTIONS STAFF. WITH THE CLOSURE OF OUR OFFICES DUE TO THE PANDEMIC, WE FACILITATED REQUESTS FOR COLLECTIONS ACCESS VIA VIRTUAL SECURE CHANNELS, PRIMARILY, MICROSOFT STREAM. IN 2020, WE LAUNCHED FIVE NEW FEATURE GALLERIES TO OUR ONLINE COLLECTION CATALOGUE PORTAL, "INSIDE THE COLLECTION" (HTTPS://COLLECTION.911MEMORIAL.ORG/), CREATING ACCESS TO ANOTHER 400+ OBJECTS. IN ADDITION, PERSONNEL IN THE MUSEUM PROGRAMS DIVISION ADDRESSED NUMEROUS PHONE AND E-MAIL CONSULTATIONS WITH OUTSIDE RESEARCHERS. A SEPARATE E-MAIL SYSTEM IMPLEMENTED IN 2014 FOR ADDRESSING GENERAL COLLECTIONS, EDUCATION, AND EXHIBITIONS QUESTIONS CONTINUES TO FACILITATE READY RESPONSES TO MORE COMMONLY POSED PUBLIC INQUIRIES. MEMBERS OF THE COLLECTIONS, EDUCATION, AND EXHIBITIONS TEAMS WERE ALSO ACTIVE AS PRODUCERS OF RESEARCH IN THEIR RESPECTIVE AREAS OF EXPERTISE, DELIVERING TALKS AT NATIONAL PROFESSIONAL CONFERENCES, LECTURING AT VARIOUS COLLEGE AND PEER INSTITUTIONAL VENUES, TEACHING ON-SITE AND VIRTUAL CLASSES, AND FACILITATING CONTENT-FOCUSED VISITS BY OUTSIDE SCHOLARS, GRADUATE STUDENTS, AND PEERS FROM HISTORIC SITES AND MUSEUMS AROUND THE WORLD. PRESERVATION FOR FUTURE GENERATIONS (III) THE MUSEUM ACTIVELY WORKS TO CONSERVE ITS COLLECTION THROUGH PROACTIVE, BEST-PRACTICE STANDARDS FOR THE CORRECT HANDLING AND STORAGE OF MUSEUM COLLECTIONS OF DIVERSE MEDIA. FOR EXAMPLE, NEW ACQUISITIONS ARE REHOUSED AND STORED USING ARCHIVAL MATERIALS. ENVIRONMENTAL AND SECURITY CONTROLS ARE ALSO IN PLACE IN STORAGE AND EXHIBITION SPACES TO ENSURE THE SAFETY OF THE COLLECTION. ONLY TRAINED AND AUTHORIZED PERSONNEL MAY HANDLE COLLECTION OBJECTS. IN 2020, THE MUSEUM'S CONSERVATORS CARRIED OUT ROTATIONS OF VULNERABLE OBJECTS IN THE HISTORICAL EXHIBITION TO REDUCE DAMAGE THAT LONG-TERM DISPLAY CAN CAUSE. OBJECTS TAKEN OFF VIEW WERE REPLACED BY NARRATIVE-APPROPRIATE ALTERNATIVES SELECTED BY THE CURATORIAL TEAM. PRIOR TO BEING EXHIBITED, THE CONDITION OF EACH OBJECT WAS CAREFULLY ASSESSED AND DOCUMENTED. SOME MINOR CONSERVATION TREATMENT WAS REQUIRED TO PREPARE SOME OBJECTS FOR EXHIBITION. CONSERVATORS ALSO CREATED FACSIMILES FOR SELECT VULNERABLE COLLECTION ITEMS SCHEDULED TO BE TAKEN OFF VIEW FOR CONSERVATION REASONS AND THAT NARRATIVELY COULD NOT BE SUBSTITUTED. TIED TO AN INDEPENDENT PROJECT FUNDED BY AMERICAN EXPRESS, THE MUSEUM CONSERVATORS CONTINUED WITH THEIR IN-DEPTH RESEARCH AND CLOSE EXAMINATION OF A LARGE, SURVIVING SEGMENT OF THE SLURRY WALL, A SECTION OF THE PERIMETER WALL THAT PERFORMED AS A WATER-BLOCKING BARRIER BETWEEN THE HUDSON RIVER AND WORLD TRADE CENTER'S ORIGINALLY EXCAVATED "BATHTUB." THIS PROJECT HAS YIELDED IMPORTANT DATA ABOUT THE CORROSION CONDITIONS OF THE SLURRY WALL'S EMBEDDED METALLIC ELEMENTS, THE DEGRADATION MECHANISMS THAT ACCELERATE THESE CONDITIONS, AND DEBONDING BETWEEN CEMENTITIOUS MATERIALS. THE DATA GLEANED WILL BE USED TO DEVELOP MONITORING PROTOCOLS AND PRESERVATION STRATEGIES TO ADDRESS MOISTURE SEEPAGE AND OTHER RISK-BASED INTERVENTIONS TO PROTECT THE INTEGRITY OF THE ARTIFACT. LOAN OR EXCHANGE PROGRAMS (IV) IN 2020, THE MUSEUM ORGANIZED ONE LOAN FROM ITS COLLECTIONS TO GRACIE MANSION, THE OFFICIAL RESIDENCE OF THE MAYOR OF NEW YORK CITY FOR AN EXHIBITION TITLED "CATALYST: ART AND SOCIAL CHANGE". ADDITIONALLY, THE MUSEUM SECURED FOUR NEW INCOMING LOANS FOR DISPLAY IN VARIOUS ON-SITE EXHIBITIONS. THE ORGANIZATION CONTINUES TO BUILD ITS PERMANENT COLLECTION AND HAS ADOPTED A COLLECTIONS MANAGEMENT POLICY TO DEFINE THE SCOPE AND INTELLECTUAL FRAMEWORK OF ASSETS AND THE PROCEDURES BY WHICH THESE MATERIALS ARE ACCESSIONED, CATALOGUED, AND PRESERVED. THAT DOCUMENT, REVIEWED AND UPDATED AS NEEDED ONCE EVERY FEW YEARS, WAS MOST RECENTLY MODIFIED IN 2018 IN PREPARATION FOR THE MUSEUM'S SUBMISSION OF KEY POLICY AND PROCEDURAL DOCUMENTS FOR ITS FIRST-TIME ACCREDITATION REVIEW BY THE AMERICAN ALLIANCE OF MUSEUMS. THROUGH LEADERSHIP OF THE BOARD AND STAFF, THE ORGANIZATION STRIVES TO ESTABLISH, PRESERVE, AND DOCUMENT PRIMARY RECORDS, MATERIAL EVIDENCE, SPOKEN TESTIMONY, AND OTHER WIDE-RANGING CULTURAL DOCUMENTATION RELATED TO THE SEPTEMBER 11, 2001 AND FEBRUARY 26, 1993 TERRORIST ATTACKS, THE HISTORICAL CONTEXT LEADING UP TO THEM, AND THEIR AFTERMATH AND ONGOING REPERCUSSIONS. THE ORGANIZATION ALSO COLLECTS ARTIFACTS, SPOKEN REMEMBRANCES, AND OTHER MATERIALS THAT HONOR AND COMMEMORATE THE VICTIMS OF THE SEPTEMBER 11, 2001 AND FEBRUARY 26, 1993 TERRORIST ATTACKS AND THEIR LEGACIES. THE ORGANIZATION MAKES ITS COLLECTION AVAILABLE AS LOANS TO OTHER MUSEUMS AND PRESENTING INSTITUTIONS, IN THE U.S. AND ABROAD, THAT MEET OUR SECURITY AND ENVIRONMENTAL CRITERIA. THE COLLECTION IS ALSO AVAILABLE, THROUGH ITS CATALOGUE AND BY APPOINTMENT, TO THE PUBLIC FOR RESEARCH PURPOSES AND IN COOPERATION WITH OUR PROFESSIONAL STAFF AND SCHOOL EDUCATORS FOR THE CREATION OF LESSON PLANS THAT ARE THEN MADE AVAILABLE THROUGH OUR WEBSITE. THE MUSEUM'S COLLECTIONS ARE ALSO USED IN EDUCATIONAL AND PUBLIC PROGRAMS AND WIDE-RANGING WEB-BASED CONTENT COMMUNICATIONS FOR THE BENEFIT OF VISITORS. IN 2020, THE ORGANIZATION SPENT $76,230 ON ACQUISITIONS OF COLLECTION ITEMS. THIS INCLUDED A PAYMENT FOR A SINGULAR, LIFE-SIZED POLAROID PORTRAIT BY TIME-LIFE PHOTOGRAPHER JOE MCNALLY FROM HIS 2001 SERIES, A SIXTH AND FINAL PAYMENT FOR WOLFGANG STAEHLE'S UNIQUE, TIME-BASED MEDIA ARTWORK THAT WAS PURCHASED IN INSTALLMENTS, 10 PRINT AND DIGITAL PHOTOGRAPHS FROM THE PHOTOGRAPHER ALLEN TANNENBAUM FROM "9/11: STILL KILLING THE HIDDEN VICTIMS SERIES", AND A WOODBLOCK PRINT BY THE ARTIST CHARLES MILEY TITLED "T'WAS RANGDA SET THE BIRDS AFIRE I". THESE PURCHASED ACQUISITIONS WERE FUNDED IN PART BY BOARD-ALLOCATED FUNDS ANNUALLY HELD IN A RESTRICTED, ROLL-OVER ACQUISITIONS LINE.
PART X, LINE 2:	THE ORGANIZATION RECOGNIZES THE EFFECT OF INCOME TAX POSITIONS ONLY IF THOSE POSITIONS ARE MORE LIKELY THAN NOT TO BE SUSTAINED. MANAGEMENT HAS DETERMINED THAT THE ORGANIZATION HAD NO UNCERTAIN TAX POSITIONS THAT WOULD REQUIRE FINANCIAL STATEMENT RECOGNITION OR DISCLOSURE. THE ORGANIZATION IS NO LONGER SUBJECT TO EXAMINATION BY THE APPLICABLE TAXING JURISDICTIONS FOR YEARS PRIOR TO 2017.

FORM 990, PART I, LINE 1, DESCRIPTION OF ORGANIZATION MISSION:	THE TERRORIST ATTACKS OF SEPTEMBER 11, 2001 AND FEBRUARY 26, 1993. RESPECTING THIS SITE MADE SACRED THROUGH LOSS, THE MEMORIAL & MUSEUM REMEMBERS AND HONORS THE 2,983 VICTIMS OF THESE ATTACKS AND ALL THOSE WHO RISKED THEIR LIVES TO SAVE OTHERS. IT FURTHER RECOGNIZES THE THOUSANDS WHO SURVIVED AND ALL WHO MANIFESTED EXTRAORDINARY COMPASSION AND LEADERSHIP IN THE WAKE OF THE ATTACKS. DEMONSTRATING THE CONSEQUENCES OF TERRORISM ON INDIVIDUAL LIVES AND ITS IMPACT ON COMMUNITIES AT THE LOCAL, NATIONAL, AND INTERNATIONAL LEVELS, THE MEMORIAL & MUSEUM ATTESTS TO THE TRIUMPH OF HUMAN DIGNITY OVER HUMAN DEPRAVITY AND AFFIRMS AN UNWAVERING COMMITMENT TO THE FUNDAMENTAL VALUE OF HUMAN LIFE. "MAY THE LIVES REMEMBERED, THE DEEDS RECOGNIZED, AND THE SPIRIT REAWAKENED BE ETERNAL BEACONS, WHICH REAFFIRM RESPECT FOR LIFE, STRENGTHEN OUR RESOLVE TO PRESERVE FREEDOM, AND INSPIRE AN END TO HATRED, IGNORANCE AND INTOLERANCE." THE NATIONAL SEPTEMBER 11 MEMORIAL & MUSEUM (9/11 MEMORIAL & MUSEUM) BEGAN JANUARY ON A STRONG FOOTING THAT WAS SUSTAINED THROUGH THE BETTER PART OF THE FIRST QUARTER, EXCEEDING PROJECTIONS ON BOTH ATTENDANCE AND EARNED REVENUE AND CONTINUING TO OFFER ROBUST EDUCATIONAL PROGRAMMING. THEN CAME COVID-19, AND LIKE SO MANY OTHER CULTURAL ORGANIZATIONS, THE 9/11 MEMORIAL & MUSEUM FACED THE UNIMAGINABLE REALITY OF HAVING TO CLOSE TO THE PUBLIC IN MID-MARCH. THROUGH FOUR MONTHS OF MEMORIAL CLOSURE AND SIX MONTHS OF MUSEUM CLOSURE, THE ORGANIZATION LIVED ITS BUSINESS CONTINUITY PLAN IN REAL TIME AND NAVIGATED UNCHARTED WATERS, LEARNING HOW TO WORK REMOTELY AND CONVERT ON-SITE PROGRAMMING TO VIRTUAL FORMATS, ALL THE WHILE FACING UNPRECEDENTED FINANCIAL CHALLENGES AS THE PRIMARY SOURCE OF OPERATING SUPPORT REVENUE GENERATED BY THE MUSEUM COLLAPSED ENTIRELY. THE INSTITUTION IMPLEMENTED NECESSARY BUDGET CUTS IN MARCH, WITH FURTHER SIGNIFICANT AND DIFFICULT REDUCTIONS IN JUNE. TO ACHIEVE THE BUDGETARY REDUCTIONS, SENIOR MANAGERIAL AND EXECUTIVE STAFF TOGETHER WITH THE BOARD OF TRUSTEES ASSESSED ALL OPERATIONAL AND PROGRAMMATIC AREAS, CLASSIFYING EACH AS RETAINED, REDUCED, OR SUSPENDED. THE INSTITUTION STROVE TO MAINTAIN ALL CORE OPERATIONAL AND PROGRAMMATIC COMMITMENTS. WHEREVER POSSIBLE, DEPARTMENTS ADAPTED ACTIVITIES AND INITIATIVES NOT CONDUCIVE TO PRODUCING IN THE CURRENT PANDEMIC ENVIRONMENT BY CONVERTING PREVIOUSLY IN-PERSON EVENTS AND PROGRAMS TO VIRTUAL OFFERINGS. THIS ENABLED THE INSTITUTION TO ENSURE IT WAS STILL SERVING ITS MISSION AS WELL AS ENGAGING WITH KEY STAKEHOLDERS AS MUCH AS POSSIBLE, WITH THE ADDED BENEFIT OF OFTEN REACHING A LARGER AND MORE GEOGRAPHICALLY DIVERSE AUDIENCE IN EDUCATIONAL PROGRAMMING. THANKS TO THE EXCEPTIONAL LEADERSHIP OF THE MEMORIAL & MUSEUM'S CHAIRMAN, MICHAEL R. BLOOMBERG, AND THE COMPASSIONATE GUIDANCE OF THE BOARD OF TRUSTEES, FUNDING WAS RAISED TO SUSTAIN THE INSTITUTION. THIS BOARD SUPPORT COUPLED WITH OTHER PRIVATE FUNDRAISING ALLOWED THE MEMORIAL AND MUSEUM TO OPERATE SAFELY AND SECURELY FOR THE REMAINDER OF 2020 AND THE NEXT CALENDAR YEAR. THE MEMORIAL REOPENED TO THE PUBLIC ON JULY 4, 2020, AND THE MUSEUM ON SEPTEMBER 11, 2020. THE ORGANIZATION DEVELOPED AND ADOPTED A ROBUST AND COMPREHENSIVE HEALTH AND SAFETY PLAN, WHICH IS REGULARLY UPDATED AND GOES ABOVE AND BEYOND GUIDANCE ISSUED BY THE CDC, NEW YORK STATE, AND NEW YORK CITY, AND WITH WHICH ENFORCEMENT AND COMPLIANCE HAS BEEN EXEMPLARY. FOR THOSE UNABLE TO VISIT IN PERSON IN 2020, THE INSTITUTION CONTINUED TO OFFER AND EXPAND ITS VIRTUAL PROGRAMMING. IN ADDITION TO ONLINE PUBLIC PROGRAMS, OUR LIVE, VIRTUAL TOURS OF THE MEMORIAL AND THE MUSEUM PROVIDED AN EASILY ACCESSED, INTERACTIVE EXPERIENCE FOR INDIVIDUALS, FAMILIES, AND GROUPS. THE INSTITUTION ALSO LAUNCHED VIRTUAL FIELD TRIPS FOR STUDENTS IN GRADES 3-12 AND ONLINE PROFESSIONAL DEVELOPMENT PROGRAMS FOR EDUCATORS AND FOR CIVIC AGENCIES. THE MUSEUM'S ABILITY TO KEEP ITS COLLECTIONS SAFE AND SECURE, ROUTINELY MONITORED, AND PROPERLY CLEANED ON SITE IN THE MUSEUM AND AT OUR TWO OFFSITE COLLECTIONS STORAGE FACILITIES, REMAINED UNCHANGED, DESPITE THE MONTHS OF CLOSURE. STAFF REMOTELY MONITORED FOR BOTH CLIMATE CONTROL AND SECURITY AND CONTINUED OUR MONTHLY PEST INSPECTIONS WITH EXPERT VENDORS AT THE MUSEUM, MANA FINE ARTS, AND OUR STORAGE FACILITY IN ROTTERDAM, NY. DESPITE BUDGET CUTS ELSEWHERE, THE MUSEUM MAINTAINED ITS COLLECTIONS INSURANCE AND RISK MANAGEMENT POLICIES AS PRIORITY COMMITMENTS, WITHOUT INTERRUPTION AND WITHOUT CHANGES TO THE COVERAGE. IN HONORING ITS FOUNDATIONAL MISSION AND CONSISTENT WITH THE STRATEGIC PLAN, THE 9/11 MEMORIAL & MUSEUM CONTINUED ITS COMMITMENT IN 2020 TO ADVANCING INSTITUTIONAL IMPACT IN FOUR KEY PROGRAMMATIC AREAS: - HONORING THROUGH COMMEMORATION BY HOSTING ANNUAL ANNIVERSARY REMEMBRANCE CEREMONIES PAYING TRIBUTE TO THE VICTIMS OF THE ATTACKS OF SEPTEMBER 11, 2001 AND FEBRUARY 26, 1993, AS WELL AS OBSERVING THE CONCLUSION OF RESCUE AND RECOVERY EFFORTS IN THE AFTERMATH OF 9/11, AND THROUGH YEAR-ROUND, FREE ACCESS TO THE MEMORIAL, A SACRED SITE OF REMEMBRANCE AND REFLECTION; BY HOSTING OUR ANNUAL 5K VIRTUALLY AND ENCOURAGING BROADER PARTICIPATION THROUGH A NATIONWIDE RUN/WALK; AND BY ASSISTING OTHER COMMUNITIES AFFECTED BY EXTREME VIOLENCE AND MASS LOSS OF LIFE THROUGH SHARING PRACTICAL EXPERTISE IN THE DEVELOPMENT OF MEMORIALS, COMMEMORATION, COLLECTIONS AND EXHIBITIONS; - UNDERSTANDING THE ONGOING REPERCUSSIONS OF 9/11 THROUGH THE COLLECTION, PRESERVATION, EXHIBITION AND DISSEMINATION OF MATERIAL CULTURE THAT TESTIFIES TO THE ONGOING IMPLICATIONS OF THE ATTACKS AND THEIR AFTERMATH (E.G., HIGHLIGHTING THE PUBLIC HEALTH ISSUES AFFECTING TENS OF THOUSANDS STRICKEN WITH 9/11-RELATED ILLNESSES, WHO ARE NOW ESPECIALLY VULNERABLE TO COVID-19); - EDUCATING A NEW GENERATION WITH NO LIVED MEMORY OF THE 9/11 ATTACKS WHO NEED THE TOOLS AND PERSPECTIVE TO NEGOTIATE A WORLD DEFINED IN MANY WAYS BY THE ATTACKS AND THEIR CONSEQUENCES; AND, - BUILDING A MORE SECURE WORLD BY INCREASING PUBLIC AWARENESS OF POST-9/11 THREATS AND LEVERAGING OUR INSTITUTIONAL CONVENING POWER TO PROVIDE EDUCATIONAL, NETWORKING, AND PARTNERSHIP OPPORTUNITIES FOR THOSE CHARGED WITH ENSURING PUBLIC SAFETY AND SECURITY. THE EXTRAORDINARY EVENTS OF 2020 PRESENTED UNIQUE CHALLENGES FOR AN ORGANIZATION WHOSE MISSION IS SO INTRINSICALLY LINKED TO A HIGHLY SPECIFIC PHYSICAL LOCATION. EVEN THROUGH MONTHS OF CLOSURE, STAFF'S COMMITMENT TO SHARING STORIES OF INSPIRATION AND HOPE, REMEMBERING THOSE WHO WERE KILLED, AND EDUCATING THE NEXT GENERATION HAD NEVER BEEN MORE RELEVANT. THE COMMEMORATION OF THE 19TH ANNIVERSARY OF THE 9/11 ATTACKS IN SEPTEMBER 2020 DREW 344,146 PARTICIPANTS TO THE ANNUAL ANNIVERSARY IN THE SCHOOLS WEBINAR, FROM ALL 50 STATES, TWO U.S. TERRITORIES, AND OVER 35 COUNTRIES. THE COLLECTIONS TEAM ACQUIRED MORE THAN 600 ITEMS, RAISING THE COLLECTION HOLDINGS TO MORE THAN 73,000. PUBLIC PROGRAMS, BOTH ONSITE PRE-PANDEMIC AND ONLINE SINCE CLOSURE AND AFTER REOPENING, REACHED MORE THAN 2,300 PEOPLE. THE 9/11 MEMORIAL & MUSEUM CONTINUED TO ADAPT AS NECESSARY IN THE FACE OF UNEXPECTED CHALLENGES, BUT THE INSTITUTIONAL COMMITMENT TO MISSION, ADHERENCE TO PROFESSIONAL MUSEOLOGICAL STANDARDS, AND DEDICATED STEWARDSHIP OF BOTH FINANCIAL AND COLLECTIONS RESOURCES REMAINED UNCHANGED THROUGH THE CRUCIBLE OF THE CORONAVIRUS PANDEMIC.
