In June 2010, members of the CSHL community celebrated the completion of an expansion and renovation of the Carnegie building. In addition to a new state-of-the-art climate-controlled vault for storage of precious archival collections that trace the history of molecular biology and genetics, the updated building also boasts an annex named for CSHL alumnus and benefactor Waclaw Syzbalski, Ph.D. Nobelist Sydney Brenner attended the opening ceremony and generously donated his archives to CSHL the same year.
