Ralph Wright, 74, a printer who rose to be an assistant secretary of labor and head of the Washington office of the International Labor Organization, died Tuesday in Daytona Beach, Fla. He had suffered from cancer.

Mr. Wright was assistant secretary of labor from 1948 to 1953 under President Harry S. Truman. He then joined the Washington office of the ILO as its labor counselor. The ILO is an agency of the United Nations that is concerned with labor matters throughout the world.

In 1959, Mr. Wright became head of the ILO office here and held that position until his retirement in 1972.He then moved from Silver Spring to Daytona Beach.

Mr. Wright was born in Concord, N.C. He began his training as a printer while attending school in Thomasville, N.C. He joined the International Typographical Union in 1920, and moved to New York City the following year. He worked at virtually all of the newspapers in New York, including The Times and The Daily News.

In 1936, he was elected a business representative of New York Typographical Union No. 6. He remained a representative of the local until his appointment as assistant secretary of labor. From 1944 to 1948, he also was executive secretary of the New York Allied Printing Trades Council, which included several printers unions.

Mr. Wright was also a member of the Typographical Union Club of Brooklyn, N.Y., the Association of Former International Civil Servants, the American Association of Retired Persons, Manor Country Club in Norbeck, and Riviera Country Club in Daytona Beach.

Mr. Wright's survivors include his wife, Lavina, of the home in Daytona Beach; four sisters, Pearl Brown and Catherine Poston, both of Lexington, N.C., Lila Tice, of Greensboro, N.C., and Sybil Bramson, of Miami, Fla.; a half-sister, Phyllis Ellington, of Reidsville, N.C., and a half-brother, Junior Shoaf, of Lexington.

The family suggests that expressions of sympathy be in the form of contributions to the Union Printers Home, Colorado Springs, Colo.
