Founded in 1981, Interleaf was a company that created software products for the technical publishing creation and distribution process. Its initial product was the first commercial document processor that integrated text and graphics editing, producing WYSIWYG ("what you see is what you get") output at near-typeset quality.[1] It also had early products in the document management, electronic publishing, and Web publishing spaces. Interleaf's "Active Documents" functionality, integrated into its text and graphics editing products in the early 1990s, was the first to give document creators programmatic access (via LISP) to virtually all of the document's elements, structures, and software capabilities.[2]

Broadvision acquired Interleaf in January 2000.[3] The latest version of the publishing software (i.e. TPS) is called QuickSilver.

Interleaf's headquarters was in Cambridge, Massachusetts and later moved to Waltham, Massachusetts.



Interleaf was founded by David Boucher and Harry George in 1981. Boucher served as chief executive officer from 1981 until 1992; George served as chief financial officer. Earlier, both were among the founders of Kurzweil Computer Products. Other early personnel came from NBI and Wang Labs. The company initially produced "turnkey" systems, that is, combinations of hardware and software integrated by the company.[4] It initially ran on workstations from Sun Microsystems and Apollo Computers, but later ported its software to workstations made by Digital Equipment Corporation, HP, IBM and SGI, and later still, to the Apple Macintosh II and the IBM personal computer.
