Marsh Stanley Marshall, 78, the retired president, board chairman and chief executive officer of the Ginn & Co. office supply concern, died of a degenerative neurological disorder Jan. 26 at his home in Washington.

Mr. Marshall became a junior partner in what became Ginn & Co. in 1951. He bought out his partner in 1965. By the time he sold Ginn's to the Hillman companies in 1982, its revenue had grown to more than $120 million.

Under Mr. Marshall's direction, the business had grown from just another Washington office supply store to a national leader in the office supply industry with retail stores in Baltimore, Richmond and Philadelphia, in addition to the Washington area.

Ginn's also included a modern distribution facility in Hyattsville, a mail-order operation and a computer-driven inventory system. Through subsidiaries such as George F. Muth Co. and Ring Temporaries, it was involved in such businesses as art supplies, office temporary workers and the manufacture of discount office furniture. Mr. Marshall also co-founded and served as board chairman of DataTel, a Northern Virginia software company.

In 1964, he was elected president of the National Stationers and Office Equipment Association. Over the years, he also served as head of the D.C. political action arm of the Greater Washington Board of Trade and also sat on the board's economic development committee. He was on the boards of First Union Bank of Washington and First American Bank of Washington.

He served on the boards of the Kennedy Center, the National Symphony Orchestra, and Georgetown University's Vincent T. Lombardi Cancer Center. He was a member of the Metropolitan and Columbia country clubs.

Mr. Marshall, who came to Washington in 1948, was born in St. Charles, Ill. He was a chemistry graduate of Harvard University, from which he received a master's degree in business administration in 1948.

During World War II, he served as a field artillery officer in Gen. George S. Patton's Third Army in Europe. Mr. Marshall, who attained the rank of lieutenant colonel, remained in the Army reserve until the mid-1950s.

Before joining Ginn's, Mr. Marshall worked in the import-export business.

His wife, the former Mary Jane Gallagher, whom he married in 1946, died in 1990.

Survivors include a son, Marsh Jr., of Washington; three daughters, Maura Christina Marshall of Chevy Chase, Jenifer Marshall Lippincott of Weston, Mass., and Donna Marshall Constantinople of Washington; and eight grandchildren.
