Robert G. Baldwin, the creator of the nationally syndicated comic strip, "Freddy," died Tuesday at the Washington Hospital Center. He was 64 years old.

Mr. Baldwin, a portrait artist as well as a cartoonist, was born in the District and attended the Corcoran School of Art where he graduated in 1935. He met Helen Limon, his wife, there.

During the depression, Mr. Baldwin traveled around the country on freight trains earning his way by painting portraits and caricatures.

He worked for the Army Map Service during World War II and afterward, he worked in comic book factories in New York, drawing cartoons.

In the early 1950s, Mr. Baldwin worked for the Central Intelligence Agency in the Far East as a director of graphics, a job that required him to visually depict plans for new mechanical devices.

It was while living in the Far East that Mr. Baldwin began working on the "Freddy" cartoon strip. He once said that "Freddy" was influenced by his children and their experiences, although the characters did not represent them.

Considered a maverick who frequently scrapped with authority, Mr. Baldwin left his CIA job in the Far East about 1956, returned to Washington and soon after set out for New York City to sell his cartoon strip to the George Matthew Adams Syndicate. "Freddy" is now carried by the Field Newspaper syndicate.

Mr. Baldwin's, son, Joel, and his wife Jane, will continue drawing the strip.

Considered a lover of animals by his friends and family, Mr. Baldwin spent hours painting and sculpting animals.

He is survived by his wife, Helen, four sons, Mark, of Surry, Maine, Jeffrey and Tommy, both of the District, and Joel of New Mexico; a daughter, Anne Marie, of the District; two sisters, Lois Egeli of Leonardtown, Md., and Grace Hefner, of Fort Pierce, Fla.; and four grandchildren.
