The Cailloux Foundation was established in 1994 by Floyd and Kathleen Cailloux to perpetuate their philanthropic vision.
Floyd was Chairman of the Executive Committee at Keystone International for 30 years after acquiring a controlling interest of Keystone Valve in 1968 and other valve companies in subsequent years which later became Keystone International. The company was sold after Floyd’s death. Keystone and its divisions are now owned by Emerson Electric (EMR).
Kathleen gave to many charities in her lifetime. In Kerrville, she gave funds to build a new humane society facility, to build a new business school and activity center at Schreiner University, and to remodel the Kerrville Municipal Auditorium, which now bears her name. She also helped fund the Humane Society of the United States, the new Gladney Center for Adoption in Fort Worth and genetic cancer research at M.D. Anderson in Houston. In 2007, Kathleen died at the age of 92 in Kerrville. The Cailloux Foundation is not associated with The Kathleen C. Cailloux Family Foundation.
