The doctoral thesis completed by Sigve Tjøtta at the University of Oslo in 1960 examined non-linear effects in sound fields, specifically focusing on vorticity generation and streaming patterns. This foundational academic work preceded a career spanning over four decades, during which he established a significant presence in Norwegian higher education and specialized research circles.
Academic Formation
Born in 1930 in Klepp Municipality, Tjøtta pursued his education at the University of Oslo, where he earned a cand.real. degree in 1954 followed by his doctorate six years later. His formative academic years included periods as a research assistant between 1954 and 1960. He further broadened his exposure to international research environments through time spent at Brown University from 1956 to 1957 and at the Max Planck Institute. During this period, he studied under advisors including Johan Peter Holtsmark.

In 1960, Tjøtta accepted an appointment as docent at the University of Bergen, earning a promotion to professor in 1963. Succeeded to the chair formerly held by Oddvar Bjørgum, he oversaw the institution’s applied mathematics curriculum. His primary research interests encompassed plasma physics, non-linear acoustics, hydroacoustics, and acoustic streaming. He also contributed to the field through visiting scholar work at the University of Texas.
Administrative and Professional Standing
Beyond his teaching duties, Tjøtta served as dean of the Faculty of Mathematics and Natural Sciences from 1975 to 1977. He held committee roles within the NAVF and NTVF, and participated in the national committee for the International Union of Theoretical and Applied Mechanics. Recognition for his work included a prize in underwater acoustics awarded by the French Academy of Sciences, which he shared with his wife and colleague, Jacqueline Naze. He was elected a fellow of the Acoustical Society of America and became a member of the Norwegian Academy of Science and Letters. In 2002, he received the rank of Knight, First Class of the Royal Norwegian Order of St. Olav.
