Comics legend Joe Kubert has passed away after a period of hospitalization.  He was 85.  A member of the Halls of Fame of both the Eisner Awards and the Harvey Awards, Kubert’s career spanned nearly 70 years, beginning in the early Golden Age and continuing until last year.  He spent much of that time doing work for DC, where his work on the characters Hawkman, Sgt. Rock, and Tarzan are legendary. He was DC's director of publications from 1967 to 1976.  He also co-created the character Tor, which was published by a number of publishers, most recently DC. 
But perhaps Kubert’s biggest contribution to comics came with the establishment of the Kubert School in 1976, devoted to training artists in cartooning and graphic art. Its many graduates populate the ranks of working comic creators for major companies. 
Kubert’s sons Adam and Andy are also well known comic artists.   

UPDATE: 
DC Entertainment Co-publishers Dan DiDio and Jim Lee released the following statement on Monday:
 
For those of us who knew him personally, as well as those of us who knew him primarily for his remarkable talent and impact on our industry over the years, Joe Kubert was part of the DC family. On behalf of our executive team, as well as everyone at DC Entertainment who cares about Joe and the whole Kubert family, we send our prayers, our sympathy and our deepest appreciation for everything he’s contributed to comics over the course of his life and career. Until the very end, Joe was creating art that will live on for generations and we will all miss him deeply.
