Kaufmann was born in Hollywood, California in 1973.[2][3] His father, William J. Kaufmann III, was an astrophysicist who served as director of the Griffith Observatory from 1970 to 1974, and also a writer of several books about physics.[4] His mother is a clinical psychologist.[5]
After college, Kaufmann lived in the Pacific Northwest before moving to Oakland, California in the early 2000s, where he has resided since.[9] Shortly after his return to the Bay Area, he switched from oil painting to watercolor.[6] He has contributed wildlife artwork to a variety of publications.[5] He was an arts writer for the East Bay Express, an alt weekly serving the East Bay.[10] Beginning in 2009, the brand Juniper Ridge employed Kaufmann as its "chief storyteller"; he eventually quit after he "got sick of selling shit."[6] He later collaborated with the Swedish denim brand Indigofera on a line of natural-fabric clothing.[11] He has worked as a tattoo artist for several years, dating back to his time living in the Pacific Northwest.[6] While he was preparing The California Field Atlas, he only took breaks to go on hikes or to work at a tattoo parlor in Oakland.[12]
Kaufmann is a conservationist and has given talks across California on ecology and preservation of nature.[13]
In 2017, the Berkeley nonprofit Heyday Books published Kaufmann's first book, The California Field Atlas. The book was a surprise commercial success: it sold out of its first two printings, generating pent-up demand, and became a regional bestseller.[14] It was a recipient of numerous California book awards.[15]
His next book, The State of Water: Understanding California's Most Precious Resource, was released in June 2019.[16] It will be followed by The California Lands trilogy, consisting of The Forests of California (Fall 2019), The Coasts of California (Spring 2020), and The Deserts of California (Fall 2020).[17]
