James Lee "Jim" Fergason was born on a farm near the small town of Wakenda, Carroll County, Missouri.[4]
He was educated in a one-room schoolhouse until the 7th grade when his family moved to the county seat of Carrollton. The Fergason family had something of a reputation for educational over achievement. One grandfather graduated from college at age fifteen, while two of Fergason's older brothers studied chemical engineering and electrical engineering respectively. A cousin was an agricultural engineer who had over 100 patents for his machinery inventions.[5]
Following his graduation from Carrollton High School in 1952 he enrolled at the
Professional career
After his discharge from the Army, Fergason was hired by Westinghouse Research Laboratories in Pennsylvania. At Westinghouse he began groundbreaking work with cholesteric liquid crystals, forming the first industrial research group into the practical uses of the technology. For this work Fergason earned his first patent (U.S. patent 3,114,836) in 1963. Among the later uses for his research and first patent were the 1970s pop culture icon the mood ring, and the Liquid crystal thermometer.[6]
In June 1966, Fergason joined the

Death
Fergason died at age 74.[where?] He was survived by his wife Dora and their four children, Teresa, Jeffrey, John and Susan, and his 11 grandchildren.[1][3]
