    Description: Description: http://www.asbmr.org/image.axd?id=643469a8-f4a7-481a-aac4-8085dd961999&t=634396062236230000We mourn the loss of long-time ASBMR member David Simmons, Ph.D. Dr. Simmons passed away in St Louis on April 19, 2011, at the age of 80. He had a distinguished and productive career with pioneering research contributions in osteoporosis, biomaterials, and bone induction. He was also a pioneer in the use of marrow stromal cells to study osteoblast differentiation. In his career at the University of Texas Medical Branch and Washington University in St. Louis, he mentored many orthopaedic surgeons and basic science postdoctoral fellows. He also served as an investigator in skeletal unloading projects with NASA. His career was marked with many achievements, including the first definition! of the effect of estrogen on bone cell lineage and on bone cell collagen, the first use of the chick-quail chimeric model demonstrating derivation of osteoblasts from fixed mesenchymal cells, and osteoclast derivation from circulating granulocytic precursor elements. Dr. Simmons was just as passionate about music as he was science and was an accomplished jazz pianist.

    Dr. Simmons was a kind and gentle person who will be missed by his friends and colleagues around the world.
