American astronomer Halton Christian Arp passed away in Munich, Germany, on December 28. He was 86. Arp was a world-renowned expert on interacting and merging galaxies. His 1966 book Atlas of Peculiar Galaxies helped astronomers realize how galaxies change over time. It contains photographs of 338 nearby galaxies that astronomers could not classify into one of the traditional shapes for those objects. Arp was born March 21, 1927, in New York City. He received a bachelor’s degree from Harvard University in 1949 and a Ph.D. from the California Institute of Technology in 1953. He then became a Fellow of the Carnegie Institution of Washington. During his stint there, Arp conducted research at Mount Wilson Observatory and Palomar Mountain Observatory, both in California. Arp became a Research Assistant at the University of Indiana in 1955. In 1957, he took a position as an astronomer at Palomar Mountain Observatory where he worked for 29 years. In 1983, he moved to Germany to join the staff of the Max Planck Institute of Astrophysics. One of Arp’s best-known scientific arguments was against the Big Bang theory, which posits a rapid expansion of all things from a hot dense state. He often spoke and wrote about what he saw as the flaws of that theory. Arp is survived by four daughters.
In Memorium - David Stevens

David was a long-time active member of the Berkeley-Sakai Association. His wife, Sally, is a member of the Berkeley-Sakai Association Board and their daughter, Molly, participated in the Berkeley-Sakai student exchange in 1984. David joined the Lawrence Berkeley Laboratory as a computer programmer and became Head of the Department. David loved music, enjoyed acting in Town and Gown, was an avid puzzler and loved to travel, especially to Japan. He participated in all of our Goodwill programs, was a wealth of knowledge about Japan, had a great sense of humor and was fun to travel with. He wrote wonderful journals about our trips and in the past few years organized and edited our yearly newsletter. We thank David, and his family, for all the years of contribution. He is missed by all of us and by the many friends he has in Sakai, Japan.
