Gideon E. Moore

Gideon E. Moore was born in 1842 in Philadelphia.  He lost his hearing over time when he was an older child.  Moore preferred to use writing to communicate.  However, he could read lips.  The Deaf community did not accept him because he did not become deaf until he was an older child.  He also struggled to communicate with hearing people. He was profoundly deaf when he started college.

His first discovery was a new mineral.  He found it in New Jersey.  He studied many different characteristics of the mineral such as the hardness, color, and specific gravity.  He named the mineral Brushite after his favorite teacher.

He also studied and documented the characteristics of a new mineral that was eventually named Metacinnabarite.  After that he selected by the government to study sorghum after the Civil War.  Since there was a shortage of sugar cane, the government wanted him to study how to make it into sugar for little money.
