Jan Kraus, a long-time member of the University of Colorado Department of Pediatrics faculty, passed away on the morning of July 4^th at the age of 77 after a long and difficult battle with lung cancer.  A Czech born in London during the second world war, Jan received a PhD in biochemistry from the University of Basel and, following several years of productive inborn errors research in the department of genetics at Yale University School of Medicine, he fell in love with the Colorado mountains and was recruited to join the CU faculty in 1989. 

His research focused on the inborn errors of propionic acidemia and homocystinuria due to cystathionine beta-synthase deficiency, beginning with studying their biochemical and molecular bases and pathogenesis, and eventually progressing to systematic studies of how they might be treated.  Earlier this year he was able to see the first patients treated with the novel enzyme replacement therapy that his laboratory group developed.  Jan was recognized internationally as a brilliant and tireless investigator.  He was also a good friend, and he will be missed.
