Gad Rausing

[1] In 1995 Gad bought out his brother's interest in the company in what was at the time the most extensive private buyout in Europe.

[2] Rausing had a lifelong passion for archaeology and the humanities and was an accomplished scholar, earning his PhD from the University of Lund in 1967 with a dissertation on Scandinavian pre-historic bows and arrow-heads.

[3][4] In addition to his work as deputy managing director at Tetra Pak he was a frequent lecturer at the Institute of Archaeology at Lund University and the author of several books.

[6] The tetrahedron subsequently became the central product of Tetra Pak, which was founded in 1951 as a subsidiary to Åkerlund & Rausing.

[11] Rausing's passion for the humanities led to his frequent sponsorship of various research projects, among others the excavation of the 10th Century Viking trading town of Birka outside Stockholm.
