for more interesting facts, news and projects! .
Otis Boykin was born in 1920 in Dallas, Texas. His mother was a maid, who died of heart failure when Otis was a year old. This inspired him to make the pacemaker. His father Walter was a carpenter, who later became a minister.
He attended Fisk University on a scholarship and worked as a laboratory assistant at the university's nearby aerospace laboratory. He then moved to Chicago, where he studied at Illinois Institute of Technology but dropped out after two years; He was discovered and mentored by Dr. Denton Deere, an engineer and inventor with his own laboratory.
He graduated from Fisk University in 1941 and got a job as a laboratory assistant, testing automatic aircraft controls. In 1944,
He later started his own company, Boykin-Fruth Inc. The firm Boykin-Fruth, Inc., would collaborate on a number of projects.
Boykin patented 28 electronic devices. One of his early inventions was an improved wire resistor, which had reduced inductance and reactance, due to the physical arrangement of the wire.
Other notable inventions include a variable resistor used in guided missiles and small component thick-film resistors for computers.
Boykin's most famous invention was likely a control unit for the artificial cardiac pacemaker.
The device essentially uses electrical impulses to maintain a regular heartbeat.
Boykin died of heart failure in Chicago at 1982.
