David Lambert Lack (July 16, 1910 - March 12, 1973) was a British ornithologist and biologist.


Lack was born in London and educated at Gresham's School, Norfolk and Magdalene College, Cambridge where he studied Natural Sciences. He was a teacher until 1940, taking a year off to study bird behaviour on the Galapagos Islands. During World War Two he was involved in early work on radar. In 1945 he became Director of the Edward Grey Institute of Field Ornithology.


Lack's scientific research included work on population biology and density dependent regulation. He wrote a number of books, including The Life of the Robin (1943) and Swifts in a Tower (1956).

David developed normally just as his brothers did but but then things he had learned started to disappear like drinking from a cup, less and less eye contact, wanting to play alone and lack of words.(David is still non verbal) We took him to the family doctor then to a pediatrician.
David's behavior was getting worse, head banging, falling to the floor, flapping his hands in front of his eyes he would sometimes stare with glossy eyes then start to cry as though he were frightened the suddenly stop then start to laugh so hard he couldn't walk.
David has a lot of little "neat" things he does that some would consider "strange" but this was David and I was learning that all these little things he did is what made David who he is......my special boy.
