Albert N. Jefferson, a radio disc jockey in the Baltimore-Washington area for 25 years and an independent record promoter, died Jan. 4 at his home in Washington. He was 93.

The cause was Alzheimer’s disease, his daughter Linda Jefferson Mason said.

Mr. Jefferson started to work as a disc jockey in Atlantic City in 1953 after singing in male chorus groups. Two years later, he began his career as a DJ in Washington at the WUST Radio Music Hall (now the location of the Nightclub 9:30) and then moved to WOOK-AM. He spent most of his career at WWIN-FM in Baltimore before retiring in 1977.

Mr. Jefferson then partnered with promoter and marketer Max Kidd to start a Washington-based record-promotion business called Al and the Kidd. Mr. Jefferson worked at the label for three years before retiring again in 1980 to take care of his wife of 47 years, the former Lillie Mae James, after she had a stroke. She died in 2002.

Albert Nathaniel Jefferson was born in Baltimore. He did not serve in World War II because of a leg injury from playing sports as a teenager, his family said.

Survivors include six daughters, Linda Mason of Washington, Jackie Dorothy of Temple Hills, Md., Lilette Brown of Laurel, Md., Noelle Reeder of Randallstown, Md., Alva Jordan of Washington and Joyce Brown of Virginia Beach; 17 grandchildren; 14 great-grandchildren; and two great-great-grandchildren.
