Abraham Louis (Pop) Hillman, who operated grocery stores here for many years, died Saturday at the Carriage Hill nursing home in Silver Spring after a brief illness. He celebrated his 100th birthday last October.

Mr. Hillman, once the operator of a prosperous flour mill in Poland, abandoned the ruined enterprise during World War I, and took his wife and children across war-torn Europe, eventually reaching the United States.

After coming to Washington he and his family opened a grocery store at 98 D St. SW. Later, in the early 1930s, the family moved the business to 319 First St. SW. He became semi-retired about 30 years ago.

During periods of ecnomic hardship, family members said, Mr. Hillman became known for extending credit to his customers, many of whom continued to visit him at his home after he left the business.

Mr. Hillman was a member of Congregation Ohev Sholom, and was known as a scholar in Judiac Law.

His wife, Hinda, died several years ago. Survivors include a daughter, Thelma Tarasuk, of Miami Beach, three sons, Charles of Washington and Joseph and Jack A., both of Chevy Chase, and six grandchildren, eight great grandchildren, eight great grandchildren and 11 great-great grandchildren.
