David Keilin FRS[1] (21 March 1887 – 27 February
1963) was a British Jewish scientist focusing mainly                         David Keilin
on entomology.[3]
Background and education
He was born in Moscow in 1887 and his family
returned to Warsaw early in his youth.[4] He did not
attend school until age ten due to ill health and asthma.
Only seven years later, in 1904, he enrolled in the
University of Liège. He later studied at Magdalene
College, Cambridge, and became a British citizen.

Copley Medal in 1951.
Legacy
The Keilin Memorial Lecture[7] of the Biochemical Society began in 1964 in his memory, and recipients
and the subject of their talk is selected by a committee reflecting Keilin's interests in bioenergetics,
electron transfer and mitochondrial biology. A medal with his profile, a financial award and an
opportunity for research publication is also awarded. In 2020, the recipient was the University of
Cambridge's Prof Judy Hirst.[8]
