[1] Her parents were Florence Maude and William Richard David who were both Elementary School head teachers.
[3] David received a scholarship and continued her studies with Karl Pearson at University College, London, as his research assistant.
Working for Karl Pearson, F. N. David computed solutions to complicated multiple integrals, and the distribution of the correlation coefficients.
During World War II, David worked as an Experimental Officer in the Ordnance Board for the Ministry of Supply, a Senior Statistician for the Research and Experiments Department for the Ministry of Home Security; a Member of the Land Mines Committee of the Scientific Advisory Council, and as a Scientific Advisor on Mines to the Military Experimental Establishment.
David died of lung cancer on 23 July 1993 in Kensington, Contra Costa County, California.
[11] David's research resulted in advances in combinatorics, including a clear exposition of complicated methods.
She wrote a book on history of probability, using problems thought of by famous mathematicians and scientists like Cardano and Galileo.
This most common randomizer of ancient times is a predecessor of the die: the astragalus or talus is the 'knucklebone' or heel bone of a running animal.
In creatures such as deer, horse, oxen, sheep and hartebeest this bone is so formed that when it is thrown to land on a level surface it can come to rest in only four ways.
