Established in 1999 as the TR100, the annual list recognizes outstanding innovators who are younger than 35. The awards span a wide range of fields, including biotechnology, materials, computer hardware, energy, transportation, communications, and the Web. We are searching for individuals whose superb technical work promises to shape the coming decades. Our goal is to recognize the development of new technology or the creative application of existing technologies to solve problems. We also reward ingenious and elegant work that matters to the world at large—not just to peers in a particular field or industry.
