Subject: David Wheeler
The Times (London), December 24, 2004.
"A pioneer of the Edsac computer at Cambridge who helped to develop
programming language"
DAVID WHEELER was one of the generation of mathematicians and engineers who
were drawn to the newly emerging discipline of computer science in the period
immediately after the Second World War. As a member of the team working with
Maurice Wilkes on Cambridge's Edsac (Electronic Delay Storage Automatic
Computer), he was responsible for the system that provided instructions to the
computer, and the innovations he made at the time still form the basis of
modern computer programming.
Wheeler's "initial orders" allowed Edsac instructions to be provided in a
simple language rather than by writing binary numbers, and made it possible for
non-specialists to begin to write programs. This was the first "assembly
language" and was the direct precursor of every modern programming language,
all of which derive from the desire to let programmers write instructions in a
legible form that can then be translated into computer-readable binary.
As the first programmer for Edsac, Wheeler invented ways of working which have
now become standard. He realised that lines of program code could often be
reused, and created the subroutine and the idea of keeping frequently-needed
subroutines in a separate library which could be called on as necessary. He
also developed the "Wheeler Jump" to allow a program to pass control to a
subroutine, the precursor of the "goto" statement known to everyone who has
ever written a program in Basic.
Wheeler was an inspiring teacher who helped to develop computer science
teaching at Cambridge from its inception in 1953, when the Diploma in Computer
Science was launched as the world's first taught course in computing. Many of
his research students now occupy senior positions in major computer companies,
or have made their own significant contributions to computer science, including
the development of new programming languages.
David John Wheeler was born in 1927 in Birmingham. He was one of many children
evacuated from major cities during the period of heavy bombing in the Second
World War. In 1945 he was awarded a scholarship to Trinity College, Cambridge,
where he read mathematics and graduated in 1948. During this period Maurice
Wilkes was working in the reopened Mathematical Laboratory, as the Computer
Laboratory was known until 1970, on a project to build a stored-program
electronic computer called Edsac. In 1947 Wheeler joined a group of students
working with Wilkes, and after graduation he became the lab's second
post-graduate student.
The first program was run on Edsac in March 1949, incorporating many of
Wheeler's innovations in its program system. These included the "initial
orders", a program which could translate simple commands into the binary
instructions needed by the computer. This allowed Edsac to be programmed by
non-specialists and marked the first step in the development of programming
languages. Edsac was not the first computer to store and run a program, because
Manchester University's "Baby" had been doing so since June 1948, but Wheeler's
work meant that Edsac could be made available to researchers outside the
Mathematical Laboratory.
Experience with writing programs for Edsac led Wheeler and his colleagues
Maurice Wilkes and Stanley Gill to publish the first book for programmers, The
Preparation of Programs for an Electronic Digital Computer, in 1951, and
Wheeler received the first doctorate awarded by the lab in the same year.
However, by the time he heard that he had been awarded a two-year research
fellowship at Trinity College he had accepted a post as assistant professor at
the University of Illinois, home of the Ordvac (Ordnance Discrete Variable
Automatic Computer), the world's fastest computer at the time. Wheeler worked
on the programming system for Ordvac and its successor, the Illiac.
He returned to Cambridge in 1953, taking up his deferred fellowship and
returning to the Mathematical Laboratory. Although most of the design work on
Edsac 2, the successor to the original Edsac, had been completed, he quickly
took on a key role defining its programming system and the basic set of
commands that the computer could carry out -- what is now called an "instruction
set". Edsac 2 went into service in 1958.
In 1955 Joyce Blackler, a research student in applied mathematics, began using
Edsac for her work and met David Wheeler. They married in August 1957.
Wheeler spent the rest of his career in Cambridge, although he returned to
Illinois in 1959 for a brief period, during which his son Martin was born. In
Cambridge he worked on the Titan computer, which replaced Edsac 2 in 1964, and
he made significant contributions to work in computer networks, data
compression techniques and computer security. His daughters Lois and Alison
were born in Cambridge.
He became a Fellow of Darwin College in 1965 and spent 1966 at the University
of California in Berkeley, working on ways to connect online terminals to
mainframe computers. In 1968 he worked for a period at Bell Labs, the foremost
commercial computing research institution of the time, on data compression
techniques. He became Professor of Computer Science in 1977.
He retired in 1994 but remained an active member of the Computer Laboratory
until his death, despite increasing loss of vision caused by age-related
macular degeneration.
David Wheeler was a private man who was not well known outside the academic
computer science community, but his significant contribution to modern
computing was widely acknowledged within the field. He was elected a fellow of
the British Computer Society in 1970, and in 1981 he became one of the earliest
computer scientists to be elected a Fellow of the Royal Society. In 1985 the
Institute of Electrical and Electronic Engineers awarded him the Pioneer Medal
"for assembly language programming", and last year he was made a fellow of the
Computer History Museum.
He is survived by his wife, Joyce, and by their three children.
David John Wheeler, computer scientist, was born on February 9, 1927. He died
on December 13, 2004, aged 77.

Subject: Czech Institute Best Paper
The paper P. Solin, K. Segeth: Non-uniqueness of almost
unidirectional inviscid compressible flow, Appl. Math. 49 (2004), 247
- 268 was awarded by the publishers, Mathematical Institute of the
Academy of Sciences of the Czech Republic in Prague, as the best
scientific paper published by a member of the Institute in Appl. Math.
in 2004. The second author, Karel Segeth (segeth@math.cas.cz), is the
member of the Institute, while the first author, Pavel Solin
(solin@utep.edu), is now at the University of Texas at El Paso.
The authors seek the origins of the non-unique behavior of gases
which can be observed in certain axisymmetric nozzle geometries under
special flow regimes. For this purpose they use several versions of
the compressible Euler equations. It turns out that the main reason
for the non-uniqueness is hidden in the energy decomposition into its
internal and kinetic parts, and their complementary behavior. They
show that a bifurcation can occur only at flow regimes with the Mach
number equal to one (sonic states). Analytical quasi-one-dimensional
results are supplemented by quasi-one-dimensional and axisymmetric
three-dimensional finite volume computations. Good agreement between
quasi-one-dimensional and axisymmetric results, including the
presence of multiple stationary solutions, is presented for
axisymmetric nozzles.
