Jacob "Jack" Morris, a beloved swimming instructor with a career spanning seven decades whose Pittsburgh-area students ranged from special-needs youngsters to senior citizens and included an Olympian and a governor's children, died Sunday.

Mr. Morris, of Highland Park, was 89. Though fit for most of his life, he had not been the same since heart surgery in 2003. He died at UPMC Shadyside.

"He was the guy who really got my swimming career started," said Al Wiggins, who came in seventh in the 100-meter backstroke at the 1956 Olympics in Melbourne, Australia.

Mr. Wiggins, 73, of Ligonier, trained under Mr. Morris while at Pittsburgh Allderdice High School before going on to swimming success at Ohio State University.

"He wasn't just a swimming coach. He was a people person who had the ability to get you to do things you didn't really want to do, but nevertheless ended up doing because that was what was required," Mr. Wiggins said.

Despite declining health in his later years, Mr. Morris still managed to instruct a handful of students at poolside until about 2006.

One of them was Joel Smalley, 75, of Oakland. Mr. Morris taught Mr. Smalley's children to swim decades earlier and then helped get the father back into shape starting in 1999 following surgery on Mr. Smalley's leg.

Mr. Morris assembled a dedicated following among swimming students and their parents, who spread his reputation through word of mouth. He also assembled a distinguished coaching record that ushered him onto the international stage.

From the late 1940s to 1962, Mr. Morris led the Young Men and Women's Hebrew Association swim team in Oakland to 100 consecutive swim meet victories.

That record and his tutelage of Mr. Wiggins could explain why in 1957 he was chosen to coach the U.S. swim team in Israel at the Maccabiah Games, the Jewish equivalent of the Olympics.

In 1963, Mr. Morris led what was then Point Park Junior College's swim team to the state junior championship. It was like a made-for-TV story that had Mr. Morris whipping the team into shape in only six months. A third of the squad had never swum before, according to a newspaper article at the time.

Mr. Morris, one of four children, grew up in Oakland. A swimming scholarship took Mr. Morris to Slippery Rock University of Pennsylvania, but the buildup to World War II interrupted. Mr. Morris entered the Army in 1941 and spent roughly four years in uniform, much of it combat in New Guinea and the Philippines.

He returned to finish his studies.

In 1948, Mr. Morris met his wife, Frances. He was directing a water show; she was in the cast. They married in 1950.

"We met in the swimming pool because that was the only place anyone could possibly have met him," Mrs. Morris, 76, said. "One's impression may be that he slept there overnight."

Indeed, Mr. Morris worked seven days a week and taught what Mrs. Morris estimated to be "literally thousands of students."

Some of those students were the children of former Pennsylvania Gov. and U.S. Attorney General Richard Thornburgh and his wife, Ginny. In an e-mail, Mr. Thornburgh called Mr. Morris "a splendid man and a patient coach."

And then there was the clapping.

Anyone who swam under Mr. Morris' watchful eye will likely recall him calling on bystanders to clap for those in the water. He did that in pools throughout the area.

Lauren Weinstein, 24, of Philadelphia, swam under Mr. Morris from the age of 5 through high school when she lived in Fox Chapel. She went on to captain the University of Pennsylvania's varsity swim team.

Ms. Weinstein said Mr. Morris taught her more than how to improve her time and refine a stroke. He taught her life lessons about being positive, patient and persistent.

"I have his voice in my head," Ms. Weinstein said.

In addition to his wife, Mr. Morris is survived by sons Michael of Los Angeles and Daniel of Naples, Fla.; and a sister, Mollie Morris of Pittsburgh.

Ralph Schugar Chapel handled the arrangements. Mr. Morris was interred at Beth Shalom Cemetery.
