Joel Greenberg is an educational technology consultant with 35 years’ experience in the field. He received
his PhD degree in numerical mathematics from the University of Manchester (UMIST) in 1973. He
worked for the Open University for over 33 years, and held a number of senior management positions
at director level. He also lectures and writes about Bletchley Park and its role in the Second World
War, as well as conducting tours of the site. He is author of a biography of Gordon Welchman, one of
Bletchley Park’s key figures throughout the war. Current projects include an authorized biography of
Alastair Denniston, the first head of GCHQ.
Simon Greenish, MBE, is a Chartered Civil Engineer and was initially a project manager. In 1995 he
joined the Royal Air Force Museum to mastermind a £30 million development, and became Director
of Collections in 2005. Subsequently he was appointed Director of Bletchley Park when it was in mon-
etary difficulties. Over six years, he secured the trust financially and the site’s historical importance is
now widely recognized. He raised £10 million to undertake repairs and support development after he
retired in 2012. He was appointed MBE in 2013 for services to English Heritage and holds an honorary
degree from the University of Bedfordshire.
Peter Hilton (1923–2010) won a scholarship to The Queen’s College, Oxford in 1940. With knowledge
of German, he arrived at Bletchley Park in early 1942, initially working on Naval Enigma in Hut 8.
In late 1942, he started work on German teleprinter ciphers, including ‘Tunny’; an early member
of the ‘Testery’, he also liaised with the ‘Newmanry’. Hilton obtained his doctorate in 1949 from
Oxford University, supervised by J. H. C. Whitehead. In 1958, he became the Mason Professor of
Pure Mathematics at the University of Birmingham, moving to the United States in 1962 for profes-
sorial posts at Cornell University and elsewhere. His research interests included algebraic topology,
homological algebra, categorical algebra, and mathematics education, with 15 books and over 600
articles.
Eleanor Ireland was born in Berkhamsted, England, in 1926. After graduating, she moved to London,
where she joined the Women’s Royal Naval Service (WRNS) in 1944. As a member of the WRNS, she
was stationed at Bletchley Park to be part of a top secret group of engineers, mathematicians, and
programmers working together to break codes during the Second World War. At Bletchley Park she
operated the early Colossus computers until the end of the war. After the war she became an artist and
illustrator, studying at the Regent Street Polytechnic School of Art.
David Leavitt is an American writer of novels, short stories, and non-fiction. He graduated from Yale
