In 1981, when Jobs was in charge of Macintosh development, Chris Espinosa, one of Apple’s first employees, created technical documentation for developers. As an example, to show the power of the QuickDraw API, which was responsible for rendering graphics, he decided to make a calculator.
In his opinion, the calculator‘s design was so excellent that it should have been added to the standard software set. With his brainchild, he went to Jobs. Steve didn’t like the thickness of the lines and the too dark background. He asked Chris to make some more variations and show him.
Maybe Jobs did the right thing by building his calculator.
Jobs didn’t like the new version anyway. Chris decided to do a “Build It Yourself” app. Calculator designer named after Steve Jobs. When Chris came to Steve, he appreciated his subordinate’s entrepreneurial spirit, smirked, and literally made a design he liked in 15 minutes.
