Patrick J. Kolb, 52, a retired loan management officer with the Small Business Administration, died Wednesday at his Chevy Chase home of amyotrophic lateral sclerosis, also known as Lou Gehrig's disease.

Mr. Kolb joined the SBA in 1965 and was a loan officer when he retired last year for health reason. Before that he worked in Panama for the United Fruit Co. and in Germany and Pakistan for the American Express Co.

During World War II, he served in the Navy in the Philippines.

Mr. Kolb was active in the Washington Sangerbund, a German choral group, and served as the group's treasurer. He also was a member of the 44 Club of Gonzaga High School.

He attended Christ the King Catholic Church in Silver Spring.

Survivors include his wife, Anna Maria, a daughter, Annemaire, a son, Patrick, and his mother, Sarah Kolb, all of the home in Chevy Chase; another son, Thomas, of Germany, and three brothers, Dr. Earl J., of Carmel, Calif., James, of Rockville, and Thomas of Kensington.
