He was an immigrant from Russia. He had been a doctor in the Red Army, first during the siege of Leningrad and then in the siege of Stalingrad, two pivotal events of World War II.

At age 93, Semen Buslovich was killed Friday as he crossed the street in Montgomery County.

Buslovich was one of 12 pedestrians who were struck and two who were killed in the county in less than 72 hours, from last Tuesday through Friday. Police cited the figures Monday while offering safety recommendations to motorists and pedestrians.

Buslovich was killed shortly before 7 a.m. as he crossed Newport Mill Road in the Kensington area, where he lived, police said. He was struck by three vehicles.

Family members recalled him as a man of great vitality, who walked regularly and was undeterred by hip replacement surgery he underwent several months ago.

The surgery was necessary, relatives said, because his hip was fractured when was struck by a car earlier this year.

His stepdaughter, Yelena Gorina, and his grandson, Max Buslovich, said the elder Buslovich was returning from a 7-Eleven store, where he had purchased a money order. Gorina said he intended to send a $5 donation to a charity that aids the families of slain police officers.

“He was interested in people,” Gorina said. “He did whatever he could.”

Buslovich was in medical school in Leningrad, now St. Petersburg, when the Germans invaded the Soviet Union during World War II. Although he volunteered for service on the front lines, Gorina said, he was sent back to medical school.

He practiced medicine in the army under conditions of great privation inside Leningrad during the German siege of the city. Near death from starvation, he was evacuated and sent to Stalingrad, where another decisive battle was fought, his stepdaughter said.

Family members recalled accounts of surgeries carried out under the most difficult conditions. And of narrow escapes from death and injury.

He worked in the “equivalent of MASH” Garina said, referring to the mobile army surgical hospitals that became familiar to many through the TV series.

As the war went on, he reached Berlin with Soviet forces.

“He was like a book of stories,” his grandson said.

After the war, Buslovich studied and practiced in the army, and outside, as a civilian. ””He saved lives,” his stepdaughter said.

In October 1991, he came to this country.

He left Russia with a heavy heart, his stepdaughter said. It was a country he had served under difficult circumstances.

But, “he always loved America,” she added, and “he always said what a wonderful country America is.”

According to police, Buslovich was killed as he crossed the south lanes of Newport Mill Road near Lawrence Avenue. He was struck by a southbound car, and then two northbound cars, police said. He died at the scene.

His stepdaughter said the family had two consolations. “He was not a man for a nursing home,” she said. And in a way, she said, “he died like a soldier,” on an errand to help others.

In last week’s other pedestrian fatality, a 61-year-old woman was struck by a RideOn bus Wednesday just before 6 p.m. at Halpine Road and Rockville Pike, police said. They said she was crossing Rockville Pike when she was hit by the bus, which was trying to turn onto the pike. Jila Hamidieh, a Rockville resident, died of her injuries in a hospital Friday evening.

In their recommendations, issued as winter darkness comes earlier, police reminded motorists that pedestrians can be all but invisible at night or in bad weather.

Pedestrians, in turn, were asked to be alert and were reminded that they should not assume that they can be seen by drivers.
