L Peter Deutsch

L Peter German ( born August 7, 1946 in Boston, originally Laurence Peter German ) is an American computer scientist and others the initial developer of Ghostscript and founder of the associated company Aladdin Enterprises. He is also the author of several RFCs. On 12 September 2007 German shortened his first name to Laurence L ( without the dot ). Many of his earlier releases were previously published already with abbreviated first name under L. Peter German.


He is the son of the physicist Martin German, studied from 1964 at the University of California, Berkeley and reached in June 1973 with his work An interactive program verifier Ph.D. in Computer Science.

From 1971 to 1986 he worked at the Xerox Palo Alto Research Center ( Xerox PARC ). In 1981 he was part of the Smalltalk development group. In the following years he became more and more frustrated as the project result was not published. In the years 1983 and 1984, he found himself outside of Xerox PARC for another job at the beginning of 1986 and decided to leave the company. Before ( 1984) he published the book Efficient Implementation of the Smalltalk-80 system. In 1986, he began to develop Ghostscript (a free PostScript implementation ) for the GNU project and founded Aladdin Enterprises to Ghostscript to market commercially. ( Was a spin-off from Xerox PARC with the Smalltalk placed on the market ), he also worked for ParcPlace. In 1991 he moved to Sun Microsystems.

In 1992 he received the ACM Software System Award for his Interlisp - work.

In 1994, he left Sun Microsystems, The Seven Fallacies of Distributed Computing wrote ( in German about the seven fallacies in the distributed computing, by James Gosling at eight fallacies extended) and was a Fellow of the ACM.

As a retiree is dedicated to the German Composition. This motivated, he engaged until 2014 within the MusicXML community.
