Aldus Corporation was a software company founded in Seattle by Paul Brainerd in 1984 that developed PageMaker, one of the earliest desktop publishing (DTP) software products, which was released in July of 1985. The company is named after fifteenth-century Venetian printer Aldus Manutius. Three former Aldus executives (Jeremy Jaech, Dave Walter, and Ted Johnson) left the company to establish Axon Corporation, later known as Visio Corporation, in 1990 and created a product which later became known as Microsoft Office Visio. In 1995, Adobe acquired Aldus and continued to publish PageMaker until 2001.
