Bill Atkinson, who pioneered the idea and implementation of the graphical user interface at Apple in the 1970s and 80s and also brought us HyperCard, died of pancreatic cancer on June 5, 2025 at the age of 74. 

Born William Dana Atkinson in Ottumwa, Iowa, on March 17, 1951, he grew up in Los Gatos, California and earned his undergraduate degree from the University of California, San Diego, where Jef Raskin, who would go on to develop the Apple Macintosh, was one of his professors. Although Atkinson had embarked on a PhD in neurobiology at the University of Washington, when he was  invited by Raskin to visit Apple, Steve Jobs persuaded him to join the company by telling him:

“Think how fun it is to surf on the front edge of a wave, and how not-fun to dog paddle on the tail edge of the same wave. Come down here and make a dent in the universe.” 

At Apple, Atkinson developed and implemented QuickDraw, a revolutionary 2D graphics library that was the technological engine behind the graphical user interfaces of both the Apple Lisa and Macintosh. He was the principal designer and developer of the GUI of the Apple Lisa, which when it was released in 1983 was the first Apple computer to feature a mouse and an icon-driven interface.

Then as a key member of the original Apple Macintosh development team he came up with many aspects of the user interface that we take for granted. He is credited with inventing the menu bar and pull-down menus, the double-click to open files and applications. With regard to graphics, in 1984 he  created MacPaint, a popular and groundbreaking digital drawing program bundled with the original Macintosh which introduced the features of the "tool palette". The selection lasso, a tool for selecting irregular shapes in graphics programs; "marching ants",  the animated dotted lines that indicate a selected area and "RoundRect", the rounded rectangles that became a distinctive visual element of Apple's design are all attributed to Atkinson.

In 1987, Atkinson conceived, designed, and implemented HyperCard, an early and highly influential hypermedia system which introduced the concept of hypertext navigation to everyday users, years before the World Wide Web, and is widely considered a significant precursor to modern web browsers and hypermedia systems.

In sum, Bill Atkinson's work at Apple transformed how people interacted with computers, making them more intuitive and accessible. His innovations in graphics and user interface design fundamentally shaped how we still use desktop computers.
