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.

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.

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.

How they approach the work

Named approaches extracted from this org’s sources. Where others share an approach, follow it to see the full set of orgs running it.

  • Commemoration Through Story and Artifact
    methodology: story_based_commemoration
    By integrating personal stories, artifacts, and first-person testimony with historical documentation, the Museum deepens public understanding of 9/11 and its human impact because narrative engagement fosters emotional connection and retention more effectively than factual recounting alone.
  • Experiential and Interactive Education
    methodology: experiential_education
    By using interactive technology, art-based activities, and experiential learning formats, the Museum engages younger audiences and families in understanding 9/11 because hands-on, age-appropriate participation increases comprehension and emotional resonance in ways passive observation cannot.
  • Inclusive Design for Equitable Access
    methodology: universal_access_design
    By applying universal and tactile design principles to memorial elements—such as chamfered name parapets and embossed text—the site ensures equitable access to remembrance for all visitors, because physical inclusivity reinforces dignity and shared humanity in collective mourning.
  • Service as Legacy and Civic Engagement
    methodology: civic_service_legacy
    By highlighting stories of service and civic action inspired by 9/11, the Museum transforms grief into intergenerational engagement because modeling positive responses to trauma encourages ongoing public contribution and resilience.
