Beverley Robinson, 93, a retired architect who had helped work on the plans for the National Gallery of Art here and the community of Greenbelt, died of a heart attack Sept. 7 while vacationing in Berkeley Springs, W.Va.

After retiring in 1958, Mr. Robinson turned to a career in painting. Working in watercolors, he painted more than 150 landscapes and seascapes, which were presented in five one-man shows.

Mr. Robinson was born in New York City. He was a graduate of Columbia University, earned a master of science degree in architecture from the University of Michigan and took post-graduate work at Harvard University.

After studying at the Ecole des Beaux-Arts in Paris, he taught for six years as an associate professor of art and architecture at the University of Michigan.

He helped design the Shelton Hotel in New York and worked with John Russell Pope on the design for Washingtons' National Gallery of Art. He helped develop plans for several hospitals in New York State.

Greenbelt was developed as a coordinated entity. During World War II, Mr. Robinson worked for the War Department, planning structures for military quarters. Later, he designed hospital for the Veterans Administration. He also helped plan several Washington area churches.

He is survived by his wife, the former Winnafred Corwin, of the home in Washington.

The family suggests that expressions of sympathy be in the form of contributions to the National Building Fund of the American Institute of Architects.
