Caleb F. Fox 4th, 64, industrial real estate broker

Caleb F. Fox 4th, 64, a Philadelphia industrial real estate broker, died at Massachusetts General Hospital in Boston of complications from a stroke on Sept. 14. He lived in Ambler.

A sportsman, Mr. Fox sometimes tested his limits.

When the spirit moved him, he jogged home from his Center City office - to Chestnut Hill. Ten miles. Much of it uphill.

"In the late '80s," his wife, Patricia, said, Mr. Fox made the trek "about 10 times."

And while vacationing, she said, Mr. Fox once raced his boat against the speedboat of President George H. W. Bush "up the Maine coast until the Secret Service following them started to look unhappy."

Mr. Fox's wife recalled that the presidential encounter occurred on her 50th birthday in October 2000.

"They were coming out of a tiny cove, right next to each other," Patricia Fox said of the two boats. When the Bush boat took off, her husband followed.

"They raced for about two miles," she said, but when the Secret Service uncovered a gun mounted on its trailing speedboat, "Caleb said, 'I think I'll head home.' "

The former president and her husband "saluted each other" and parted, she added.

Mr. Fox attended Chestnut Hill Academy and graduated from Middlesex, a boarding school in Concord, Mass., in 1963, she said, and then earned degrees from Trinity College in Hartford, Conn., and the Wharton School of the University of Pennsylvania.

He had been a commercial loan officer at Pennsylvania National Bank, but spent the bulk of his career, since 1978, at Binswanger Corp., where until his death he was senior vice president in the industrial division. Mr. Fox was a board member of Sunnybrook Golf Club in Plymouth Meeting and the York Paddle Tennis Club in Maine, and a member of the Temple University Investment Committee and of its administrative subcommittee.

Since 1998, he was a board member of the Episcopal Hospital Corp. and, since 1999, was the treasurer of the board of directors of Fairmount Long Term Care, which operates the City of Philadelphia's nursing home.

In the 1970s, Mr. Fox was a sergeant in the First City Troop, a unit of the Pennsylvania National Guard.

His wife said his sports included squash, rugby, paddle tennis, golf, tennis and football. He also ran in the New York City Marathon, the Marine Corps Marathon in Washington, and the Philadelphia Marathon.

Besides his wife, Mr. Fox is survived by sons C. Thayer and Timothy, and a sister, Wendy Baurmeister.

Services were to be private.
