This plaque commemorates Eugene Salas, a deaf man who worked as the first Missioner (or Missionary) at the South Australian Deaf and Dumb Mission, from 1893 until his death in 1915. It was brought from the previous building in Wright Street, and was displayed on the wall of the chapel at 262. Eugene Salas’ descendants (deaf and hearing) continue to be involved in the South Australian Deaf community today.
