Deaf biochemist Nansie Sharpless forced the
way scientists feature their presentations
at scientific conferences.
In the past scientists would give a speech
and then respond to questions and comments
from the audience.
Because of her deafness, the procedures changed.
She was allowed to give presentations via
audio-visual posters, and that audience
feedback were also posted on audio-visual.
That was during the fifties and sixties.
Not sure if this practice continues at
scientific conferences as she passed away.
