The Department of Anatomy and Cell Biology wishes to acknowledge the passing of Dr. Carl M. Feldherr. Carl received his PhD from the University of Pennsylvania and came to UF in 1967. While at UF for 36 years, he rose through the ranks to become full Professor and retired as Professor Emeritus in July 2003. He received the Faculty Research Prize in 1988 and held the Haskell Hess Professorship from 1993-2003. Carl published over sixty articles in top-tier journals including the Journal Cell Biology and Nature. His elegant and pioneering studies on protein and RNA transport between the nucleus and cytosol were highly influential and continue to underpin our current understanding of the structure and function of the nuclear envelope and nuclear pore complex. While at UF, Carl also contributed in teaching medical, dental, and graduate courses in histology and cell biology topics. Upon retirement, Carl stayed in Gainesville where he enjoyed kayaking, scuba diving, and underwater photography. His impressive collection of underwater photos includes beautiful images enjoyed by many who have received them as gifts over the years. Recently, Carl moved to Princeton to be close to his son (Dr. Andrew Feldherr), daughter-in-law (Dr. Deborah Steiner), and grandkids (Rebecca and Miriam). His pleasant nature, insights, curiosity, artistry, and uniquely dry sense of humor will be truly missed.
