I was sad to learn from Mai Gehrke, a recent visitor here in Berkeley, that
Bjarni Jansson
had very recently passed away.  Mai was a collaborator and co-author of
his.  I remember
him vividly, though I have not seen him in many years.

Below are two obituary notices and the listing from the Mathematics
Genealogy Project.
Note that the Vanderbilt obituary mentions 14 Ph.D. students.  The
Genealogy listing
should be corrected.  Can someone help?

> Bjarni J?nsson, Vanderbilt?s first Distinguished Professor of
Mathematics, died Sept.
> 30 at the age of 96.
>
> Born in Iceland, J?nsson earned his bachelor?s and doctoral degrees from
the
> University of California-Berkeley and also received an honorary degree
from the
> University of Iceland. He was internationally recognized as a leading
authority on
> universal algebra, lattice theory and algebraic logic.
>
> In his career, J?nsson authored 89 technical papers and served on the
editorial board
> of several major mathematics journals, including Algebra Universalis. He
presented
> numerous invited talks at mathematics conferences around the world. In
1974, he was an
> invited speaker at the International Congress of Mathematicians. In 2012
he was
> elected an inaugural fellow of the American Mathematical Society. He was
also the
> recipient of Vanderbilt?s Harvie Branscomb Distinguished Professor Award
in 1974 and
> the Earl Sutherland Prize for Achievement in Research in 1982.
>
> ?Bjarni J?nsson was a remarkable mathematician who made field-defining
and path-
> breaking contributions in universal algebra, lattice theory and algebraic
logic.
> Anyone who had the fortune to know him admired his integrity, kindness
and immense
> respect for colleagues and friends. His influence on my personal and
mathematical life
> has been enormous, and it is a great privilege that I have had the
opportunity to work
> with and learn from him,? said Professor Constantine Tsinakis, a
long-term colleague
> and a former chair of the mathematics department.
>
> ?To me Bjarni will always be a legend, who in his quiet, sincere,
unassuming ways
> continues to inspire uncountably many algebraists, raising questions and
re-examining
> areas that he feels would benefit from an algebraic approach,? wrote
Peter Jipsen, one
> of the doctoral students that J?nsson advised, on the occasion of his
70th birthday.
> ?While some mathematicians almost revel in stringing together long
complex arguments,
> Bjarni has constantly sought to simplify and illuminate the subjects dear
to him,? the
> professor of mathematics at Chapman University added.
>
> J?nsson came to Vanderbilt in 1966 and taught here until his retirement
in 1993. When
> he arrived, mathematics was mostly an undergraduate teaching department.
He was
> instrumental in establishing the department?s graduate program, which
presently ranks
> among the top departments in the nation, according to the latest
evaluation by the
> National Research Council. J?nsson also formed a research group in
algebra that
> attracted mathematicians from around the world and contributed
substantially to the
> high research profile that the department currently enjoys.
>
> Algebra is the study of mathematical objects and the rules for
manipulating them.
> J?nsson made his most important contributions in the area of universal
algebra. It is
> one of the most abstract subfields of algebra because it studies
algebraic structures
> in general, as opposed to specific classes of algebras, such as groups
and fields. The
> importance of his contributions is reflected by the fact that a number of
mathematical
> objects are named for him, including J?nsson and J?nsson-Tarski algebras,
Jansson
> cardinals, J?nsson terms, the J?nsson lemma and the J?nsson-Tarski
duality.
>
> During his tenure, J?nsson supervised 14 Ph.D. students. In letters they
wrote for a
> symposium in honor of his 70th birthday, which took place in Iceland in
1990, his
> former students all expressed a deep appreciation for him as a ?respected
mathematical
> guide and personal friend.?
>
> One of the first students he supervised, Steven Monk, now professor
emeritus at the
> University of Washington, recalled advice that he received from J?nsson
regarding
> teaching: ?Adventure is not in the guidebook and beauty is not on the
map. The best
> one can hope for is to be able to persuade some people to do some
traveling on their
> own.?
>
> ?Bjarni?s work and scholarly contributions will have a lasting legacy.
His name will
> forever be interwoven in the history of our department. We are honored to
have had
> him as a colleague,? noted the current department chair, Professor Mike
Neamtu.
