Louis Kalichstein, 91, manager of the old William Rosendorf fur store at 1215 G St. NW for 40 years until his retirement in 1967, died Sunday at the Willow Glen Convalescent Home in San Jose, Calif. He had hypertension.

Mr. Kalichstein was born in a part of Austrian Poland that now is in the Soviet Union. His family took him to the United States when he was a year old and he grew up in New York City and Brooklyn. He put himself through City College of New York by working as a night manager of the Western Union Telegraph Co.

In 1927, Mr. Kalichstein moved to Washington to become manager of the William Rosendorf store, where he was known to his customers and associates as "Mr. Kay." In 1967, when he retired, he moved to Laguna Hills, Calif. He moved to San Jose a year ago to be near a daughter.

In Washington, Mr. Kalichstein was active in the Better Business Bureau, the old Community Chest and Parent-Teacher Associations of the schools his children attended. He also was a Mason. For many years he was treasurer of the B'nai Israel Synagogue.

Survivors include his wife, Rose Cohen Kalichstein of San Jose; two daughters, Rita Pearl of San Jose and Emily Evershed of Washington, and three grandchildren.
