Arthur L. Kramer, a tennis enthusiast who once hosted the likes of Grand Slam champions Rod Laver and Roy Emerson in his Baltimore home, died of pneumonia Wednesday at Winkler Court hospice care in Fort Myers, Fla. He was 87.

Mr. Kramer grew up in Baltimore and graduated from City College in 1936. He went into the Army Air Forces in 1941 and was a pilot during World War II, leaving the service in 1945. When he returned to Baltimore, he joined his family's business, the Pilot Blouse Co. He married Rose Marie Porcaro in 1958.

Mr. Kramer was a sports buff who was passionate about University of Maryland athletics. He served on the athletic foundation board at the University of Maryland and was a former president of the university's Terrapin Club, an athletic booster organization.

He and his wife flew all over the world to watch Grand Slam tennis tournaments and never missed a U.S. Open in New York City. Mrs. Kramer said her husband, whose travel around the tournament circuit helped him build key contacts in the tennis world, invited tennis greats such as Laver and Emerson to Baltimore for tournaments. Mr. Kramer was also active in the Baltimore Hebrew Congregation, organizing one of the Baltimore area's first mission trips to Israel, Mrs. Kramer said.

The couple retired to Florida a decade ago.

The family is holding private graveside services for Mr. Kramer at the Hebrew Friendship Cemetery in Baltimore.

Survivors include his wife; a son, Jeffrey Kramer, of Mechanicsburg, Pa., and a granddaughter.
