Biography
Steven Chu, born on February 28, 1948, in St. Louis, Missouri, is an American physicist and former government official. He studied at Garden City High School, the University of Rochester, and the University of California, Berkeley. Chu gained worldwide recognition for his pioneering work in atomic physics, especially his research on cooling and trapping atoms with laser light, which won him the 1997 Nobel Prize in Physics along with Claude Cohen-Tannoudji and William Daniel Phillips.
Chu began his scientific career at Bell Laboratories, where he developed methods to manipulate atoms using laser technology. He later moved to the University of California, Berkeley, and Stanford University, where he studied biological systems at the single molecule level. His leadership at the Lawrence Berkeley National Laboratory boosted his reputation in the scientific world. Chu earned several prestigious awards, including the King Faisal International Prize in Science in 1993, the Arthur L. Schawlow Prize in Laser Science in 1994, and the Guggenheim Fellowship in 1996.
In 2009, Chu shifted from academia to public service when President Barack Obama appointed him as the 12th U.S. Secretary of Energy. During his time from 2009 to 2013, he pushed for more investment in renewable energy research and nuclear power to combat climate change. He introduced ideas like the 'glucose economy,' suggesting a low-carbon system where glucose from tropical plants would be a key energy source, similar to oil today.
After stepping down as Energy Secretary in April 2013, Chu went back to Stanford University as the William R. Kenan Jr. Professor of Physics and Professor of Molecular and Cellular Physiology. He continued to promote clean energy solutions and strategies to address climate change while getting back to his research. In 2019, he was President of the American Association for the Advancement of Science for a year, reinforcing his role as a leader in science. Chu was made a Foreign Member of the Royal Society in 2014, acknowledging his global contributions to physics and science policy.
Before Fame
Steven Chu grew up after World War II when the government was heavily supporting scientific research and technology was advancing quickly. During his childhood, the Space Race was in full swing, and laser technology was developing, both of which would influence his future work. After graduating from Garden City High School, Chu studied at the University of Rochester and then at the University of California, Berkeley, where he focused on physics.
In the 1970s and 1980s, atomic physics research was booming, thanks to new laser technologies that made certain experiments possible for the first time. Chu got involved in this field when laser cooling was theoretically understood but still needed practical exploration. His early work at Bell Laboratories put him at the leading edge of atomic manipulation research, paving the way for the Nobel Prize-winning discoveries he made in laser cooling and atomic trapping.
