, developing the first programming language "
Autocode", and its compiler for the
EDSAC 2 computer, for which he was awarded a PhD degree in 1963. His thesis was entitled "Automatic Programming for Digital Computers".
Software development
As a member of the staff of Cambridge University's
Mathematical Laboratory, he was joint author, with
David Barron, John Buxton, Eric Nixon, and
Christopher Strachey, of the early high-level programming language
CPL. which was subsequently developed into
BCPL which in turn influenced
B and
C.
From 1962 to 1967 he was a major contributor to the development of the Cambridge Multiple Access System that was developed for the
Titan, the prototype

Hartley was successively Junior
Research Fellow at
Churchill College, Cambridge, Fellow of
Darwin College and then
University Lecturer. He also did some pioneering work in
video-tape recorded lecturers. In 1986, he was elected a Fellow of Clare College where he is currently secretary of the Alumni Association.
Computing service
Between 1970 and 1994, Dr Hartley was director of
University of Cambridge Computing Service.
The service had been founded as the Mathematical Laboratory under the leadership of
John Lennard-Jones in 1937, although it did not become properly established until after

Moore School Lectures.
EDSAC was the result, and Wilkes also supervised Hartley's PhD.
When Dr Hartley became Director, the Mathematical Laboratory was renamed the Computer Laboratory, with separate departments for Teaching and Research, and the Computing Service. One of Dr Hartley' most notable achievements as Director between 1987 and 1992, was to conceive and design the Granta Backbone Network, a
fibre-optic network that joined up all of Cambridge's university and college sites.
Public service
From 1972 to 1974 Dr Hartley was chairman of the UK Inter-University Committee on Computing. He was a member of the Computer Board for Universities and Research Councils – which allocated government funds to purchase the large and expensive computers that the institutions needed – from 1979 to 1983 where he had special responsibility for network development. From 1981 to 1986 he was a member of the Prime Minister's Information Technology Advisory Panel. Having become a Fellow of the

(FBCS) in 1968, Dr Hartley served on its Council in 1970–73, 1977–1980 and 1988 to 1990, was a Vice-President from 1987 to 1990, Deputy President in 1998–99 and President in 1999–2000.
Since ceasing to be Director of the University Computing Service, Dr Hartley has served both private sector and public sector bodies, but the latter have predominated.
From 1994 to 1997 he was Chief Executive of the United Kingdom Education and Research Networking Association (UKERNA) whose objectives were to take responsibility for the UK academic community's networking programme, and to further opportunities with other communities, including industry.

, the UK's joint academic network, which provides computer network and related collaborative services to UK education and research, including further- and higher-education organisations and the
UK Research Councils.
From 1997 to 2002, Dr Hartley was Executive Director of the
Cambridge Crystallographic Data Centre which maintains the largest searchable database of experimentally-determined small molecule crystal structures. It performs analyses on these data and facilitates others' use.
Dr Hartley maintains strong ties with the University of Cambridge where he continues to be a Fellow of Clare College and an Honorary Member of the Computer Laboratory. He has recently become involved in the history of computing, serving for four years as Chairman of the Computer Conservation Society, a special-interest group of the British Computer Society. In 2012 he spent a year as part-time Museum Director of
The National Museum of Computing and is currently a trustee of the
EDSAC Replica Project.
