This book describes the lives and achievements of 27 disabled scientists and students of science who are overcoming obstacles and are carrying on careers and studies in their chosen field of science or engineering, graphically showing that individuals with physical disabilities can succeed in scientific and technical work. The book presents a sample cross section from a large group of successful scientists with a wide range of disabilities, describing, among others, a paraplegic electron microscopist, a world renowned expert on transplantation biology who is deaf, and a blind computer scientist. Disabled students profiled range from those about to receive their bachelor's degrees to doctoral candidates. Their disabilities range from congenital encephalopathy to cerebral palsy, and from congenital glaucoma to spinal bifida. The major objectives of the book are to illustrate possible career options open to physically disabled students and to encourage teachers and counselors (especially those in elementary and junior high schools) to help scientifically talented disabled students to get the education they need to prepare them for scientific careers.
