CHICAGO -- A jogger was struck and killed this morning in the city's Jackson Park neighborhood.

74-year-old Gary Toback, a professor of medicine at the University of Chicago, was running at 6:40 this morning near the south end of Jackson Park Golf Course when a 40-year-old woman driving a Jeep lost control of her vehicle. Her SUV hit Toback as he approached the corner of 67th and Bennett. The Jeep rolled over and landed on its roof. Toback was killed almost instantly, leaving an enormous loss within the University of Chicago and the field of nephrology.

Dr. Marshall Lindheimer brought Toback to Hyde Park in 1974; he had noticed his talents years before when Toback was an intern at Case Western Reserve. He completed medical school at NYU and a fellowship at Harvard. He did not limit his studies, however, to the practice of medicine.

"He was a scholar," Lindheimer said. "He was an MD/PhD with a biochemistry degree and very serious. Like all good academic physician scientists, he had ideas and knew how to bring them to patient care."

Toback's clinical interests included renal failure and hypertension. But as an active researcher, colleagues say his most recent study of certain proteins held promising commercial possibilities in cancer treatment.

The University issued this statement: "We have lost an institutional leader who represented the University of Chicago's values and aspirations...he was a treasured colleague, friend, mentor, leader and physician."

Lindheimer says that Toback's tenure as nephrology section chief goes to show the esteem in which he was held by colleagues, administrators and patients.

"He was a very good listener, and that is what made him so popular."

A 2-year-old girl was riding in the Jeep. She was taken to Comer Children's Hospital in good condition. Police are investigating the crash.
