Qui va sortir amb Florence Nightingale David?

Florence Nightingale David (Ivington, 23 d'agost de 1909 - Kensington, 23 de juliol de 1993), normalment coneguda com F.N. David, va ser una matemàtica i estadística britànica.

Els seus pares eren molt amics de Florence Nightingale i, quan va néixer la seva filla (un any abans de la seva mort), li van posar aquests noms. Va estudiar al Bedford College for Women (actual Royal Holloway) en el qual es va graduar en matemàtiques el 1931. A partir de 1933, va treballar al University College de Londres, en el qual va obtenir el doctorat el 1938. Durant la Segona Guerra Mundial, entre 1939 i 1945, va treballar pel govern britànic fent estadístiques de guerra. Acabada la guerra, va tornar al departament d'estadística de l'University College on va romandre fins al 1967 quan va marxar a Califòrnia per establir un departament d'estadística a la universitat de Califòrnia a Riverside. El 1977 es va retirar a Riverside, però va continuar sent professora emèrita a la universitat de Califòrnia a Berkeley fins a la seva mort el 1993.

David va publicar nou llibres entre els quals destaca Games, Gods, and Gambling (1962), en el qual fa un repàs de la història de la probabilitat i dels conceptes estadístics. També va publicar més de cent articles científics i va escriure una quinzena d'informes de guerra (que encara estant classificats com secrets) i diversos llibres blancs pel servei forestal dels Estats Units.

Evelyn Fix (January 27, 1904 – December 30, 1965) was a statistician. She was born in Duluth, Minnesota and earned her A.B. in mathematics at the University of Minnesota in 1924. One year later she earned an M.S. in education and became a high school teacher. She earned an M.A. in mathematics, also from the University of Minnesota in 1933. She obtained a Ph.D. in 1948 at the University of California, Berkeley, and joined the statistics faculty there. She was appointed as an assistant professor in 1951 and in 1963 she was promoted to professor of statistics. She died of a heart attack on December 30, 1965.

During World War II, Fix worked as a research assistant in the Mathematics Department at the University of California, Berkeley on projects conducted as part of work conducted for the "Applied Mathematics Panel of the National Defense Research Committee." Fix was one of two women who were the first assistant professors hired by the statistics group within the Mathematics Department in 1951. Statistics became a separate department in 1955. In 1951 Fix and Joseph Hodges, Jr. published their groundbreaking paper "Discriminatory Analysis. Nonparametric Discrimination: Consistency Properties," which defined the nearest neighbor rule, an important method that would go on to become a key piece of machine learning technologies, the k-Nearest Neighbor (k-NN) algorithm.

She was a Fellow of the Institute of Mathematical Statistics.
