Lloyd Kahn (born April 1, 1935) has a BA from Stanford University. During the late 1950s, while serving in the United States Air Force in Germany, Kahn ran the USAF newspaper for two years. Returning to California in 1960 to work as an insurance broker, he suddenly quit his insurance job and began work as a carpenter, eventually building four houses.

Each project became more ambitious. His first project was a sod-roof studio in Mill Valley, with succulents planted on the roof. The second was a used-wood, timber-frame Japanese/Bernard Maybeck-influenced design: a post-and-beam frame, with several -high poured concrete walls. Before these two jobs, he'd had little building experience, but quickly learned on the job. This is where he discovered the owner/builder perspective in learning to build. He tried to maintain this outlook throughout his publishing career, so he could explain building techniques to novice builders. He next got a job in Big Sur as foreman building a large post and beam house out of bridge timbers from a dismantled bridge; the main structural members were 30' long, 8' X 22" redwood beams. He then built his own home out of used lumber and hand-split shakes in Big Sur, developed a water supply, and terraced a hillside for small-scale farming.

Influenced by Buckminster Fuller, during 1968 he started building geodesic domes. This resulted in a job coordinating the building of 17 domes at Pacific High School, an alternative school in the Santa Cruz mountains. They experimented with geodesic domes made from plywood, aluminum, sprayed foam, and vinyl. Children built their own domes and lived in them. Jay Baldwin built a dome covered with vinyl pillows. When Buckminster Fuller visited the school during 1970, he commissioned Baldwin to build a replica of the dome on his property in Maine. The school received media attention.

Kahn next worked for Stewart Brand as Shelter editor for the Whole Earth Catalog. During 1970 Kahn published his first book, Domebook One, followed the next year with Domebook 2, which sold 165,000 copies. During 1971, he bought a half-acre lot in Bolinas, California, and built a shake-covered geodesic dome - later featured in Life magazine. After living in his dome for a year, Kahn decided domes didn't work well: he stopped the printing of Domebook 2 and disassembled and sold his dome. He then went in search of other (non-dome) ways to build - across the U.S.A., Ireland, and England, and the book Shelter (1973) was the result.

During the next two decades, Shelter Publications produced a series of fitness books, including Bob Anderson's Stretching (which has sold 3 million copies and is in 31 languages), Galloway's Book on Running by Olympian Jeff Galloway, and Getting Stronger by legendary bodybuilder Bill Pearl. More recently, Shelter produced StretchWare, software that reminds you to stretch at your computer.

During 2004, Kahn published Home Work: Handbuilt Shelter. Home Work summarizes the best of his work over the past 30 years photographing buildings and interviewing builders, and includes numerous buildings directly inspired by the book Shelter. The Septic Systems Owner's Manual, first published during 2000, was extensively revised in 2007. Shelter Publications' next book is The Barefoot Architect: A Manual on Green Building. Kahn is currently working on a new book, Builders of the Pacific Coast: Creative Carpentry, featuring a unique group of builders along the Pacific Coast, from California to British Columbia.

In keeping with his fitness theme, Kahn, at the age of 72, continues to surf, skateboard (longboard) and run (the Dipsea Race) competitively. He and his wife Lesley live and work in a small town on the Pacific Ocean coast north of San Francisco, California.
