Paul C. Ergler Sr., a retired Martin Marietta Corp. aeronautical engineer who later became a professor of business management at what is now Loyola University of Maryland, died Sunday of a cardiac arrest at Oak Crest Village.
The former longtime Glen Arm resident was 92.
Born in Pittsburgh and raised in Upper Darby, Pa., Dr. Ergler was a 1937 graduate of Upper Darby High School.
He attended Drexel University in Philadelphia, where as a co-op student, he earned a bachelor's degree in 1942 in aeronautical engineering.
"Because he was a co-op student, he studied for six months and worked six months," said a daughter, Jennifer E. Robinson, who lives in Monkton.
Dr. Ergler began working in 1937 for the old Glenn L. Martin Co. in Middle River, and after graduating from Drexel, began working there full time.
Because of the nature of his Martin Co. work, he was deferred from serving in the military during World War II. He spent 35 years at Martin-Marietta working on numerous aircraft and NASA projects in cutting-edge technologies. He was named quality control manager.
He retired in 1972.
In the late 1950s, Dr. Ergler returned to Drexel, where he earned a master's degree in business and earned his Ph.D in business administration from George Washington University.
He joined the faculty of what is now Loyola University of Maryland in 1966, where he taught both undergraduate and graduate business students.
"He challenged students and had a reputation for being tough as well as providing solid opportunities for learning," said Ms. Robinson.
Dr. Ergler retired from Loyola in 1994.
His wife of 45 years, the former Dorothy Pollard, died in 2003. In 2005, he married the former Eris Bailey, who died in 2010.
A resident of the Parkville retirement community since 2005, he had been a Scoutmaster and an active member of the Masons and Shrine.
Dr. Ergler was a longtime active member of St. John Evangelical Lutheran Church, 3911 Sweet Air Road, Phoenix, Baltimore County, where funeral services will be held at 11 a.m. Thursday.
In addition to his daughter, Dr. Ergler is survived by his son, Paul C. Ergler Jr. of Tampa, Fla.; another daughter, Jeanette E. Maybin of Columbia, S.C.; four grandchildren; and a great-granddaughter.
