[mizar] Grzegorz Bancerek has passed away
With deepest regret I have to announce that our colleague Grzegorz
Bancerek passed away prematurely on November 18th at age 51. Today we
accompanied Grzegorz on His last journey and united in sorrow with His
wife Ewa and two children, Bartek and Maria.
Grzegorz was an indispensable member of the Mizar team, who was
several times awarded with the Sleszynski and Lesniewski Prizes of the
Association of Mizar Users. He took part in the founding of the Mizar
Mathematical Library, and He still remains one of the most prolific Mizar
authors to date with 124 MML contributions. It must be noted that He never
avoided difficult scientific challenges. His formalizations concerned a
great variety of mathematical domains, including foundations of set
theory, topology, lattice theory, universal and many-sorted algebra, or
category theory. He was also the leader of the team-effort project aimed
to formalize the Compendium of Continuous Lattices in Mizar. Recently, His
works focused on computer science topics, most notably the analysis of
algorithms and the formalization of the metatheory of the Mizar system.
Being a mathematician by education, Grzegorz was also a self-educated
programmer who was always keen to discover new technologies and
programming techniques and to apply them in His projects. Among His
various tools and services He developed several versions of remote Mizar
processors, on-line Mizar courses and e-learning classes. But most
importantly He was the author of the current implementation of the
translation software used in automatic generation of English math text
from Mizar articles for the Formalized Mathematics journal, of which He
was the Scientific Editor. He also developed several data formats and
on-line systems to help browsing, searching, and analyzing the MML. The
powerful MML Query system was His invention intended to aid writing Mizar
articles, but also to explore and present the contents of the Mizar
library.
For the last nine years Grzegorz was struggling with severe illnesses, but
still remained active and spared no strength for the good of the Mizar
project.
Personally, I will always remember Grzegorz as a brilliant scientist and a
dedicated university teacher, but also as a very cheerful and open person
with great devotion to family life, who very much enjoyed Japanese cuisine
and loved playing the guitar classical pieces in His free time.
