Henry Brem has developed new tools and techniques that have changed the field of neurosurgery. Brem carried out the pivotal clinical study that introduced navigational imaging into the neurosurgical suite. His work led to the FDA's approval of the first image guidance computer system for intraoperative localization of tumors. Furthermore, he has changed the surgical armamentarium against brain tumors by inventing and developing Gliadel® wafers to intraoperatively deliver chemotherapy to brain tumors. His work has shown that surgeons can accurately deliver potent therapies directly at the tumor site. Henry Brem is the Harvey Cushing Professor of Neurosurgery at The Johns Hopkins University, Director of the Department of Neurosurgery, and Neurosurgeon-in-Chief. He also is a professor of Oncology, Ophthalmology, and Biomedical Engineering. Brem received his undergraduate degree from New York University, his medical degree from Harvard, and trained in neurosurgery at Columbia. At Hopkins, he has built one of the largest brain tumor research and treatment centers in the world. He reinstituted the Hunterian Neurosurgery Laboratory (originally founded by Cushing) and has trained numerous researchers who have revolutionized the fields of intraoperative imaging, angiogenesis, immunotherapy, and controlled release polymers for drug delivery to the brain. Brem has changed the surgical treatment of brain tumors by introducing new approaches for targeted therapy. He developed new classes of polymers and microchips for drug delivery that are custom synthesized for the agent being developed. The polyanhydrides, which were the first new treatments for brain tumors that the FDA had approved in 23 years, have been shown in his laboratory to be biocompatible and potent. He then designed and led the clinical trials demonstrating safety and efficacy. Brem has used his laboratory experience to design and lead many novel multi-institutional clinical trials to prove the safety and efficacy of this approach in patients with brain tumors. His work has been continuously funded by the NIH since 1982, and is currently funded by several active grants. Brem's teaching was recognized by the Hopkins Professors Award for Excellence in Teaching in 1996. In 1998 he was elected to the Institute of Medicine of the National Academy of Sciences. In 2000 he was awarded the Grass Award by the Society of Neurological Surgeons for meritorious research; in 2001 he received the Founders Award of the Controlled Release Society; in 2004 he received the New York University Distinguished Alumni Award; in 2005 he was co-recipient of the Society for Biomaterials Technology Innovation and Development Award and was named the Coleman Fellow in Life Sciences at Ben-Gurion University. In 2011 he delivered the commencement address for the Johns Hopkins University School of Medicine. He has been recognized by the Castle Connolly Guide each year from 2002 in “America’s Top Doctors”, and from 2005 – present in “America’s Top Doctors for Cancer”. In 2013, the Society for NeuroOncology and the Section on Tumors of the AANS/CNS named him as the recipient of the Abhijit Guha Award. In 2014, The Johns Hopkins University established the Henry Brem Endowed Chair in Neurosurgery.
