Germund Dahlquist
(16 January 1925 – 8 February 2005) was a
known primarily for his early contributions to the theory of
as applied to
.
Dahlquist began to study mathematics at
in 1942 at the
age of 17, where he cites the Danish mathematician
(who was living
in exile after the
during
) as a profound
influence.
He received the degree of
from Stockholm University in 1949, before
taking a break from his studies to work at the Swedish Board of Computer
Machinery (
), working on (among other things) the early
computer
, Sweden's first. During this time, he also worked with
on early numerical weather forecasts.
Dahlquist returned to Stockholm University to complete his Ph.D.,
Stability
and Error Bounds in the Numerical Solution of Ordinary Differential Equations
,
which he defended in 1958, with
and
as his
advisors.
As part of this work he introduced the
(also
introduced by Russian mathematician
the same year).
In 1959 he moved to the
(KTH), where he would
later establish what became the Department of Numerical Analysis and Computer
Science (NADA) in 1962 (now part of the School of Computer Science and
Communication), and become Sweden's first Professor of Numerical Analysis in
1963.
He helped establish the Nordic journal of numerical analysis, BIT, in
1961. In 1965 he was elected into the
(IVA).
The software package
, for
of
, was started by a couple of Dahlquist's graduate
students based upon codes developed for a graduate course at KTH.
