William DeMarco Mayo Sr., an industrial artist with AAI Corp. who was known for his highly intricate drawings of military weapons systems and vehicles, died of lymphoma Saturday at the home of a daughter in White Hall, Baltimore County. He was 74.
Mr. Mayo was born in Baltimore and raised in Sparrows Point and Glencoe. He was a 1947 graduate of McDonogh School and earned a bachelor's degree from the Maryland Institute College of Art in 1951.
He worked for three years as an illustrator at the former Glenn L. Martin Co. plant in Middle River before joining the Army in 1954 as a topographer. He went to work in 1956 as a technical artist at the Westinghouse Electric Corp. plant in Linthicum.
In 1962, Mr. Mayo joined AAI Corp. in Hunt Valley in the company's industrial division and later was promoted to the weapons and aerospace divisions. He retired from the company in 1992, and spent the next decade working as a consultant.
Mr. Mayo, who lived in Phoenix, enjoyed scavenging for unusual materials that he fashioned into sculptures and other artwork, family members said. He also enjoyed working on home-landscaping projects.
He was an active member of the AAI Retirees Association and McDonogh School Alumni Association.
A memorial Mass will be offered at 11:30 a.m. Feb. 21 at St. Mark Roman Catholic Church, 812 Reckord Road, Fallston.
Surviving are his wife of 48 years, the former Carolyn D. Meeks; three sons, William DeMarco Mayo Jr. of Fawn Grove, Pa., Christopher Mayo of New Freedom, Pa., and Gregory Mayo of Baldwin; two daughters, Kimberly A. Whichard of White Hall and Michele "Miki" Mayo of Parkton; and seven grandchildren.
