{{Short description|Canadian businessman and chemist}}
'''David Boris Pall''' (2 April 1914 – 21 September 2004), founder of [[Pall Corporation]], was the chemist who invented the [[Pall filter]] used in [[blood transfusion]]s.

==Education==
Born in 1914 in [[Thunder Bay]], [[Ontario]] of Russian immigrant parents, he grew up on a farm in [[Saskatchewan]]. He attended [[McGill University]], from which he was granted a bachelor's degree in [[chemistry]] and a [[Doctor of Philosophy|Ph.D.]] in [[physical chemistry]].

==Career==
He moved to [[New York City]] in 1938 and became a part of the [[Manhattan Project]]. Pall worked on the design a filter to separate uranium 235 from uranium 238 using [[sintered]] stainless steel mesh.<ref>{{cite web|url=http://www.fundinguniverse.com/company-histories/pall-corporation-history/|title=Pall Corporation History|website=fundinguniverse.com|access-date=8 Apr 2014}}</ref>

In 1946, he established [[Pall Corporation]].  The company's initial focus was on the development of filters for use in [[aircraft]] [[hydraulics]].  However, in 1959, when  Dr. Pall's first wife, Josephine, died of [[aplastic anemia]], he began to work on the ''Pall filter''. Mrs. Pall had undergone multiple blood transfusions in the course of an illness, which were ultimately unsuccessful. His Pall filter was designed to make blood transfusions significantly safer by filtering out [[white blood cell]]s, thereby reducing the incidence of [[transfusion reaction]]s and [[virus|viral]] infections.

Pall expanded the business, adding additional products. Today, Pall Corporation has sales in excess of $2.0 Billion.

==Achievements==
In his lifetime, Dr. Pall received over 180 [[United States Patent Law|patents]] and in 1990, he received the United States National Medal of Technology from President [[George H. W. Bush]].<ref>[https://www.nytimes.com/2004/09/26/obituaries/26pall.html David B.
