The Ronald and Maxine Linde Hall of Mathematics and Physics has a long history of philanthropic support. Built in 1923 through a cooperative venture with Southern California Edison, the facility was initially constructed to help solve emerging problems in power transmission. The first laboratory in the United States to have a million-volt power source, the facility was called the High Voltage Research Laboratory, and warmly referred to as "High Volts" by the campus community.

In the late 1950s, Caltech saw an expanding need for research and teaching space to support physics and mathematics. The facility was rebuilt with a generous contribution from the Alfred P. Sloan Foundation and dedicated as the Alfred P. Sloan Laboratory for Mathematics and Physics on December 1, 1960. It remained the Alfred P. Sloan Laboratory until 2017.

As mathematics continued to grow at Caltech, the building was again renovated to create a modernized home for the department. A generous gift from Caltech alumnus and Vice Chair ofthe Board of Trustees, Ronald Linde (MS '62, PhD '64) and his wife, Maxine, funded the renovated facility, which opened in 2018 as the Ronald and Maxine Linde Hall of Mathematics and Physics.
