Facts and Events
[REDOND~1.FTW] John Bell Ladd, like his brother, also had an inventive mind; he invented and perfected two working models of writing machines for the blind, each was demonstrated to the blind with success. There was an immediate demand for them by the blind but none but the two models were ever built. This was about the time that typewriters came into use. One necessary feature, especially for the blind, was the bell that sounded at the end of the line -a feature of all the early typewriters. He was satisfied with what he had accomplished, then he turned to something else. He would have rendered a great service to the blind had he put his efforts to the manufacture of the machines - maybe wealth for himself. References
