Solomon Kullback
Solomon Kullback( April 3, 1907 August 5, 1994) was an American cryptanalyst and mathematician, who was one of the first three employees hired by William F. Friedman at the US Army's Signal Intelligence Service( SIS) in the 1930s, along with Frank Rowlett and Abraham Sinkov.

Kullback was the Chief Scientist at the NSA until his retirement in 1962, whereupon he took a position at the George Washington University.
The Kullback – Leibler divergence is named after Kullback and Richard Leibler.

Giovanni Battista Braccelli
Giovanni Battista Bracelli or Braccelli is the name of more than one engraver and painter active in central Italy in the Baroque period, between about 1616 and 1649.
According to Filippo Baldinucci, one Giovanni Battista Braccelli studied under Giovanni Battista Paggi(" il Paggi") and was active in Genova, where he worked in the churches of and Santi Cosma e Damiano, and where he died in 1609 at the age of 25.
According to Stefano Ticozzi, he was born in 1584, became the most valued assistant to Paggi, and died before his twenty- fifth birthday.
A Florentine Giovan Batista Braccelli was a pupil and collaborator of Jacopo da Empoli.
He published in 1624 in Livorno a" Bizzarie di varie figure", a book of etchings with a dedication to Don Pietro de' Medici( who died in 1604).
Other mentions are of a Florentine Giovanni Battista Bracelli who was a pupil of Giulio Parigi, and another also known as" Brazzé" or" Il Bigio".
It is not clear whether these were different people to those above.
A collection of engravings entitled" Figure con instrumenti musicali e boscarecci", published in Rome after 1624, also bears the name Giovanni Battista Bracelli, as does a rare" Alfabeto figurato" published in Naples in 1632.

Richard Leibler
Richard A. Leibler( March 18, 1914, Chicago, Illinois – October 25, 2003, Reston, Virginia) was an American mathematician and cryptanalyst.
Richard Leibler was born in March 1914.
He received his A.M. in mathematics from Northwestern University and his Ph.D. from the University of Illinois in 1939.
While working at the National Security Agency, he and Solomon Kullback formulated the Kullback – Leibler divergence, a measure of similarity between probability distributions which has found important applications in information theory and cryptology.
Leibler is also credited by the NSA as having opened up" new methods of attack" in the celebrated VENONA code- breaking project during 1949- 1950; this may be a reference to his joint paper with Kullback, which was published in the open literature in 1951 and was immediately noted by Soviet cryptologists.
He was director of the Communications Research Division at the Institute for Defense Analyses, a captive think tank for NSA, from 1962 to 1977.
He was inducted into the NSA Hall of Honor for his efforts against the VENONA code.
