Edgar Reed Lang, 98, a retired physical chemist with Rohm & Haas Co., died Tuesday, Sept. 18, at Normandy Farms Estates in Blue Bell from complications of a recent stroke.
A native of Sioux Falls, S.D., Dr. Lang earned his bachelor's degree in chemical engineering from the South Dakota School of Mines in 1936. He earned his master's degree and doctorate in physical chemistry at Ohio State University.
He was then recruited to Rohm & Haas in Philadelphia by founder Otto Haas, Dr. Lang's daughter, Karen Lang Black, said. He received a deferment during World War II because of his critical skills and was instrumental in the Bristol production plant's winning an award for excellence.
