Gunnar Kulldorff (6 December 1927 – 25 June 2015) was a Swedish statistician, specializing in estimation theory, survey sampling and order statistics.

[1] Taking a teaching positions in the same department, he did his doctoral studies under the supervision of Carl-Erik Quensel and Harald Cramér.

[3] In 1965, Kulldorff was appointed as the first professor of statistics at the newly established Umeå University, where he also became the first dean of the Faculty of Arts and Sciences.

Seeing a need for knowledge and education about survey statistics, which had been underdeveloped during the Soviet era, he initiated a scientific exchange program between the Baltic and Nordic countries.

A few years later, this led to the creation of the Baltic-Nordic-Ukrainian Network on Survey Statistics, with annual conferences, workshops and/or summer schools.
