The funding for the De Logi Science and Technology Grants comes from the De Logi Trust. The grants are intended "to support activities that are likely to have a strong long-term impact on science and/or technology."
Dr. Walter De Logi was a remarkable man. His PhD research at Caltech (1975-1978) spanned electrical engineering and theoretical physics. After a diversion to Harvard Business School he became an entrepreneur, and created and led a sequence of successful biotech companies. He was driven by wide ranging curiosity and a deep understanding of issues in science and technology (with emphasis on biology, chemistry, physics and cosmology), and also art and architecture. De Logi died in 2014 leaving a large portion of his estate to Caltech. Under the terms of his Trust and following his wishes, "The highest priority [is] given to high-payoff high risk projects that are hard to fund in other ways", decisions about how to spend these funds are made jointly by the Caltech Administration and a self-perpetuating De Logi Approval Committee (DLAC), which is comprised of Caltech professors.
