Sustainability and social concerns were hallmarks of both his practice and his mantra as an educator. He began teaching at the University of Southern California in the early 1960s before being selected as founding chairman of the Architecture Program at California State Polytechnic University at Pomona in 1968. He established SCI-Arc in 1972, along with Thom Mayne, Jim Stafford, Glen Small, Ahde Lahti, Bill Simonian, and his wife Shelly Kappe, as an alternative to traditional architectural programs; it was originally called “The New School.”

Described by SCI-Arc director and CEO Hernan Diaz Alonso as a “transformative figure” and “outlaw” who “challenged the status quo of what was architectural education, and changed the world of architecture forever,” Kappe received several awards for his work at SCI-Arc, including the AIA’s Topaz Medallion and the Lifetime Achievement in Education Award.

In a poem commemorating Kappe’s innovative spirit, former SCI-Arc director Eric Owen Moss wrote: “Ray Kappe: The toughest task. Make something. From nothing. Not many do that. SCI-Arc, No, To SCI-Arc, Yes. An aspiration. Realized. Teach it. Draw it. Exhibit it. Lecture on it. Build it. Make it new. Ray Kappe. SCI-Arc. From nothing to something. History became the history he wrote.”
