No matter. The Volta Laboratory is a National Historic Landmark for helping the hearing impaired.
Built in 1893 by Charles Summer Tainter and Bell’s cousin Chichester Bell, the towering yellow brick and sandstone building at 35th St. NW in Georgetown, was created for the creation of technologies to help the deaf.
Alexander Graham Bell gained the first patent for the telephone in 1876, but the son and grandson of speech teachers also trained teachers for the deaf. Bell used 50,000 francs awarded by the French government to found Volta Associates that concentrated on recording and transmitting and recording sound. The group then built the Volta Lab for the business.
