The tech community recently celebrated the 31st anniversary of Windows 95, sparking discussions about its design influences, particularly regarding the potential British roots of its interface. Former Microsoft engineer Dave Plummer's post on X led to exchanges among ex-Microsoft employees, including Joe Belfiore, who clarified that the Windows taskbar was not inspired by the NeXT dock but rather by developments from the Cairo team, specifically a persistent "tray" for file transfers. The debate references Paul Fellows, who led the Arthur project at Acorn, which introduced the first "icon bar" in 1987, influencing both NeXTstep and Windows. Acorn's Arthur, initially a BASIC demo, became RISC OS by 1989, maintaining its foundational design elements. The timeline shows that Acorn's icon bar predated NeXTstep's dock and the Windows taskbar, with Windows 2.0 and OS/2 1.1 released in late 1987 and 1988, respectively, showing visual similarities to NeXTstep. The Microsoft Cairo project, which ran from 1991 to 1996, coincided with Windows NT 4 development. The Windows 95 taskbar and NeXT's dock served different functions, but their historical context is significant.
