Bjarni Jónsson (February 15, 1920 – September 30, 2016)[1] was an Icelandic mathematician and logician working in universal algebra and lattice theory. He was emeritus Distinguished Professor of Mathematics at Vanderbilt University and the honorary editor in chief of Algebra Universalis. He received his PhD in 1946 at UC Berkeley under supervision of Alfred Tarski.[2][3]

Several mathematical objects are named for him, among them Jónsson algebras, ω-Jónsson functions, Jónsson cardinals, Jónsson terms, Jónsson–Tarski algebras and Jónsson–Tarski duality.

In 2012 he became a fellow of the American Mathematical Society.[4]
