Jef Raskin
American computer scientist (1943–2005) who initiated the Macintosh project at Apple and authored The Humane Interface — Aza Raskin's father and the origin of the humane-interface tradition.
Jef Raskin was an American computer scientist, musician, and interface designer who initiated the Macintosh project at Apple in 1979 and spent his subsequent career articulating the principles of humane interface design. His 2000 book The Humane Interface remains one of the foundational texts in human-computer interaction, arguing that interfaces should conform to the patterns of human cognition rather than requiring humans to conform to the patterns of machines. His son Aza Raskin's career — including the Center for Humane Technology — can be read as the extension of this tradition into the era of engagement-optimized platforms and artificial intelligence.

Jef Raskin's intellectual contribution was the articulation of specific, testable principles for interface design oriented toward human cognitive welfare: monotony (a command should have only one way to be invoked), modelessness (the same input should always produce the same output), the elimination of surprise, and the privileging of the user's mental model over the machine's architecture. These principles informed
