 Zvonimir Janko (1932-2022)  With a deep sense of loss we would like to communicate that the world famous Croatian mathematician Zvonimir Janko passed away on April 12, 2022. He made a great impact to finite group theory and combinatorial design theory. Professor Janko was not only an expert but a nice and generous person as well, always willing to help. As such he will be overwhelmingly missed by his former students, colleagues, friends and family.  Zvonimir Janko was born on July 26, 1932, in Bjelovar, Croatia. He studied mathematics at the University of Zagreb, Croatia. After graduation he taught physics at a high school in Siroki Brijeg in Bosnia and Herzegovina, ˇ where he met his future wife Zora. He earned his PhD at the University of Zagreb in 1960. In his thesis, entitled Decomposition of some classes of nondegenerate R´edei Groups on Schreier extensions, Zvonimir Janko solved a problem posed by the Hungarian mathematician L´aszl´o R´edei.  Janko spent two years at The Austral

Ross Anderson [1] writes: Gus Simmons is one of the pioneers of cryptography and computer security. His contributions to public-key cryptography, unconditional authentication, covert channels and information hiding earned him an honorary degree, fellowship of the IACR, and election to the Rothschild chair of mathematics when he visited us in Cambridge in 1996. And this was his hobby; his day job was a mathematician at Sandia National Laboratories, where he worked on satellite imagery, arms-control treaty verification, and the command and control of nuclear weapons. During lockdown, Gus wrote a book of stories about growing up in West Virginia during the depression years of the 1930s. After he circulated it privately to a few friends in the cryptographic community, we persuaded him to put it online so everyone can read it. During this desolate time, coal mines closed and fired their workers, who took over abandoned farms and survived as best they could. Gus’s memoir is a gripping oral h
