Time Capsule at Gallaudet Building The Laying of the cornerstone of the Gallaudet Building took place on July 22, 1920. However, before the cornerstone was sealed, ASD's President at the time - Henry Perkins - Placed a time capsule inside the foundation. As he did, he addressed the audience: "A feature of this occasion is, in conformity with an old custom, the sealing up of a box containing old papers dating from the time of the founding  of the school, a city directory of today, the current newspapers, school reports, and coins of the present year. This, in a way links us to the past and with the future, an symbolizes the continuity of our body of work". This time capsule was unearthed during the demolition of the Gallaudet building on March 5, 2015 by Executive Director Jeffrey Bravin.
