Harvey B. Steinberg, 82, who practiced divorce law in Montgomery County for more than 40 years, died Feb. 21 at his daughter’s home in Derwood after a heart attack. He was a Rockville resident.

A daughter, Pamela Mayer, confirmed the death.

Mr. Steinberg was a senior partner of the Rockville law firm Miller, Steinberg & Hessler until 1999, when it closed. He then did divorce mediation for the Montgomery County Circuit Court before retiring in 2002.

He was recognized twice by Washingtonian magazine as a top area divorce lawyer.

Harvey Bert Steinberg was born in Philadelphia and, as a boy, had a cartoon column in the old Philadelphia Bulletin. He moved to Washington as a teenager and joined the Marine Corps in 1946. He was discharged in 1951 after suffering injuries during the Battle of the Chosin Reservoir during the Korean War. His military decorations included the Purple Heart.

After the war, Mr. Steinberg obtained a GED. He received a bachelor’s degree in 1955 and a law degree in 1958, both from George Washington University.

His marriages to Annette Wallace and Helen Wentz ended in divorce. A son from his first marriage, David Steinberg, died in 1961.

Survivors include a son from his first marriage, Joseph Steinberg of Santa Monica, Calif.; three children from his second marriage, Charles Steinberg of Rockville, Pamela Mayer of Derwood and William Hogan of Conway, S.C.; five grandchildren; and two great-grandchildren.
