Jef Raskin (1943-2005) was an American computer interface expert best known for his contributions to the Macintosh project at Apple. Wikipedia says,
"Parallel to the Lisa's development, a skunkworks team at Apple was working on another project. Conceived in 1979 by Jef Raskin, the Macintosh was envisioned as an affordable, easy-to-use computer for the masses, with the Lisa's graphical interface." (Wikipedia: Mac (computer), 12.28.22 UTC 09:13)
The rest of this post is some quotes from Raskin.
Ease of use
"A well-designed and humane interface does not have to be split into beginner and expert subsystems." (The Human Interface: New Directions for Designing Interactive Systems, 2000)
"An interface is humane if it is responsive to human needs and considerate of human frailties." (The Human Interface: New Directions for Designing Interactive Systems, 2000)
