Partly-printed DS, one page, 9 x 4.5, June 28, 1892. Certificate from the American Association to Promote the Teaching of Speech to the Deaf presented to Abby Stone having “been duly elected a member of The American Association to Promote the Teaching of Speech to the Deaf, and having paid the annual assessment of Two Dollars, is entitled to all the rights and privileges of membership.” Signed at the bottom in black ink, “Alexander Graham Bell,” as president of the association and countersigned by his cousin, “C. J. Bell,” as treasurer. Intersecting folds and a small stain and holes to the center (obscuring the recipient’s middle name), otherwise fine condition.
Having several family members who were deaf—including his mother and wife—Bell’s primary scientific goal was to develop equipment to assist the hearing-impaired, with the telephone and the microphone initially conceived for that very purpose. The devices were also a reflection and continuation of the work long-performed by his father with deaf-mutes. In 1890, more than a decade after he received a US patent for his invention, Bell established the American Association to Promote the Teaching of Speech to the Deaf, with the objective of promoting oral communication, and was elected the New York City-based organization’s first president. An excellent example of Bell’s focused involvement with the hearing-impaired. Pre-certified PSA/DNA and RR Auction COA.
