Jørgen Hoffmann-Jørgensen was born on 3 February 1942 in Aarhus. He completed his studies at Aarhus University in 1966 and was subsequently employed at the Department of Mathematics at the same university until his retirement in 2012. During his career he was a visiting researcher at several established universities, including Cornell, Texas A & M and Scuola Normal Superiore di Pisa.

Jørgen Hoffmann-Jørgensen's scientific work was characterized by profound insight and great originality, and he made several significant contributions, including an important result now known as the Hoffmann-Jørgensen's inequality. He is one of the pioneers in high-dimensional probability theory and was very active in this field throughout his career. This theory has been fundamental to the development of modern statistical methods for high-dimensional data, also called big data. Hoffmann-Jørgensen wrote the two-piece work Probability with a View Towards Statistics, which provides a solid mathematically based insight into some of the most important probability theory topics, and he also authored a wide range of scientific articles. From 1988 until his death, Jørgen Hoffmann-Jørgensen was co-editor of the recognised Journal of theoretical probability.

Hoffmann-Jørgensen was an excellent and committed communicator of the probability theory and its applications, which both students and audience at his public lectures experienced. Until his death he was frequently present at the Department of Mathematics.

Jørgen Hoffmann-Jørgensen was a highly appreciated colleague and employee. He will be missed by family, friends and colleagues.
