J. M. Major, 62, a retired master sergeant who served in the Army Transportation Agency at the White House and who also was a civilian motor pool adviser for the Army Reserve, died of congestive heart failure Wednesday at Physicians Memorial Hospital in LaPlata, Md.

Mr. Major lived in Waldorf for 25 years before moving to Charlotte Hall, Md., in 1974.

He was born in Marietta, Ga., grew up there and in Cumming, Ga., and entered the Army in 1937. In World War II, he worked for a shipyard in Portland, Maine, before transferring to the White House transportation agency as a chauffeur in 1944. He was a White House chauffeur until 1959, when he retired from active duty.

Mr. Major then became a civilian employe of the Army Reserve, from which he retired in 1972.

Survivors include his wife, the former Bertha L. Higgins, who he married in 1942, of Charlotte Hall; two sons, Bruce E. of Accokeek, Md., and James E. of Dale City; his stepmother, Ozelle Major; two brothers, Hurschel and Kenneth Major, and three sisters, Marie Sneed, and Irene and Lois Yarbrough, all of Cumming, Ga., and four grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to Children's Hospital National Medical Center.
