John ‘Jack’ Powell Babcock, Jr. ’45 of Rialto, Calif., died on March 14, 2010. Jack was born in 1923 and grew up in Paris, Ill. A member of Beta Theta Pi, he graduated from Mines with a professional degree in petroleum engineering before serving in the U.S. Navy as an electronics, radio, radar and sonar technician. After being discharged, he worked as a civil engineer for the highway department in his hometown of Paris, but soon moved on to start his own business, Techicraft, designing and installing television antennas, and signal distribution and high fidelity systems. In 1950 he married Ruth McKinzie. The couple moved to California in 1955, where they settled in Rialto and Jack began a 42-year career with Lockheed Aircraft Service in Ontario, Calif. An electronics aerospace engineer, he contributed to the design of numerous military and commercial aircraft, but was particularly proud of his contribution to the hospital configuration of the C-130. In the 1980s he was selected to serve on a team that assisted with the design of a personal jet for King Hussein I of Jordan, who Jack met. He retired in 1997 when Lockheed closed its Ontario operation. Known for his integrity, honor and devotion to his wife and family, Jack was predeceased by his wife after 52 years of marriage. He is survived by two daughters, Melinda and Pamela; three grandchildren; and three great-grandsons.
