Offering a thumbs-up, pointing at an object, and tracing a shape in the air 鈥攁ll of these methods of communication are fascinating to Dr. Benjamin J. Bahan, 鈥79. On April 12, the retiring professor of Deaf Studies delivered the first Gallaudet Legacy Lecture on the topic of 鈥淥ur Gestural Orientation,鈥 exploring how and why humans use their hands and bodies to express themselves.

Dean of the Faculty Dr. Khadijat K. Rashid, 鈥90, introduced Bahan, who has worked at Gallaudet since 1996. She told the audience in the I. King Jordan Student Academic Center and online that this will become an annual lecture series.

To explain the aims and origins of his work, Bahan mapped his path from Gallaudet to he Salk Institute for Biological Studies in California to Boston University and then back to Gallaudet. In the early days of his career, he and his colleagues focused exclusively on American Sign Language. But when Bahan interviewed pioneering linguist and long-time Gallaudet professor Dr. William C. Stokoe, H-鈥88, in 1999, they discussed Stokoe鈥檚 regrets. 鈥淗e wished he hadn鈥檛 used a linguistic framework, but had started with gestures,鈥 Bahan explained.

That rekindled Bahan鈥檚 interest in the area, which has grown over the past two decades. In 2017, he established Gallaudet鈥檚 Gesture Literacy Knowledge Studio as a hub for this area of research. Building a video database of gestures from around the world, Bahan has been reminded of the universality of movement in nonverbal communication. 鈥淭here is no culture that exists without nonverbal communication and gesture,鈥 he said. 鈥淚t鈥檚 in our DNA. Babies point if they want something. They reach out their hands to be held and cared for.鈥

Bahan noted that humans have walked the earth for hundreds of thousands of years. 鈥淎round 50,000 years ago, anatomy evolved for speech,鈥 he said. So gesture is what they must have used to communicate for most of that time, just as hearing people do in many situations today: when interacting with users of a different language, when stealth is required, when taking a vow of silence, or when environmental factors interfere (for instance, underwater or in a noisy place).

Several video clips helped Bahan prove how common it is for hearing people to gesture, whether it is because they鈥檙e baseball players relaying information to teammates, comedians emphasizing a point for laughs, or someone in a Zoom conversation with a relative who can鈥檛 figure out how to unmute their microphone. Bahan offered examples from multiple countries and cultures, emphasizing why further research could lead to better understanding.

鈥淕esture is the root of spoken and signed languages,鈥 Bahan said. 鈥淎t Gallaudet, we need to reclaim this field. I believe it has to be part of Gallaudet鈥檚 academic mission.鈥 Although he is retiring, he promised to visit. 鈥淎nd when I come back,鈥 he said, 鈥淚 would like to see all of you gesturing.鈥
