Albert L. Meyers, 77, professor emeritus of economics at Georgetown University's School of Foreign Service and the author of a widely used textbook on economics, died of pneumonia Saturday at Washington Adventist Hospital in Takoma Park. He had a heart ailment.

Dr. Meyers wrote his textbook, "Elements of Modern Economics," while teaching at Colgate University, where he earlier had earned a bachelor's degree. The textbook, which was used in major universities in this country in the 1930s, '40s and '50s was published in 11 languages and still is being used overseas.

He joined Georgetown's faculty in 1946, after serving as chief economist of the American Farm Bureau and principal economist of the Agriculture Department's Bureau of Agricultural Economics. He retired in 1958.

Dr. Meyers was born in North Tonawanda, N.Y., and reared in Buffalo. He earned a doctorate from Harvard University and was a member of the American Economic Association and the Association of University professors.

A former longtime resident of Chevy Chase, he lived in Silver Spring.

Survivors include his wife of 45 years, the former Majorie Castle of Silver Spring; a son, Stewart C., of Bethesda; a daughter, Susan M. Finch of Kensington, and a granddaughter.

The family suggests that expressions of sympathy be in the form of contributions in his name to Colgate Universtiy or to Harvard University.
