Lester Shubin, the Justice Department researcher who turned a DuPont fabric intended for tires into the first truly effective bulletproof vests, saving the lives of more than 3,000 law enforcement officers, died Nov. 20 after a heart attack at his Fairfax, Va., home. He was 84.

Mr. Shubin was working at the National Institute for Justice, the research and development branch of the Justice Department, in the early 1970s when DuPont came out with a fabric that was to replace steel-belting on high-speed tires.

Nicholas Montanarelli, who worked for the Army's Land Warfare Laboratory at the Aberdeen Proving Ground, told Mr. Shubin about this new substance, Kevlar, which was said to be "stronger than steel, lighter than nylon." Montanarelli obtained a couple of samples of what Mr. Shubin called "this funny yellow fabric," and the men took it and some handguns to a firing range.

"We folded it over a couple of times and shot at it. The bullets didn't go through," Mr. Shubin later told a Justice Department report on the National Institute for Justice's accomplishments.

Attempts at body armor have been around for thousands of years. Medieval knights clothed themselves head to toe in metal armor. By the World War II era, there were cloth flak jackets with metal inserts.
Kevlar was different; it worked by deforming the bullet, spreading its energy as it hit the body armor. It wasn't perfect. It protected against 80 to 85 percent of the handguns then on the market, not rifles, and a wearer could suffer bruises or broken bones. But it saved lives.
Mr. Shubin went back to the Justice Department to wrest $5 million in research money out of the bureaucracy, and Montanarelli began developing the tests. They wanted their vest to be not only strong but also lighter than earlier versions and flexible enough so that police officers and soldiers could work in it.

They put their new vest over a gelatin mold to determine how a human body might react to the impact of a handgun bullet and then drafted, as test subjects, a series of unfortunate goats.

Mr. Shubin, a native of Philadelphia, served in the Army during World War II and was among the troops that liberated the Dachau concentration camp, said his son, Harry Shubin, also of Fairfax.

Other survivors include his wife of 50 years, Zelda Loigman Shubin, and two grandchildren.
