William B. Davis, retired chief engineer at the Cambridge plant of an electronics company, died Wednesday of cancer at Dorchester General Hospital. He was 59 and had lived in Cambridge since 1968.
A mass of Christian burial for Mr. Davis will be offered at 11 a.m. tomorrow at St. Mary Refuge of Sinners Roman Catholic Church in Cambridge.
He retired about a year ago from the Airpax Corp., for which he began working on a part-time basis in 1949 in Baltimore.
The Baltimore native worked at Airpax's headquarters in Fort Lauderdale, Fla., from 1957 until he moved to Cambridge.
A former president of the Fort Lauderdale and Cambridge Lions clubs, he also headed the Lions organization on the Eastern Shore.
He is survived by his wife of 36 years, the former Charlotte Miller; a daughter, Monica J. Davis of Pensacola, Fla.; five sons, William B. Davis Jr. of Fredericksburg, Va., Joseph M. Davis of Easton, Michael P. Davis of Salisbury, and Robert C. Davis and Brian T. Davis, both of Cambridge; two sisters, Joan Signorelli of San Jose, Calif., and Janet Giordano of East New Market; a brother, Paul E. Davis Jr. of Chamblee, Ga.; and five grandchildren.
