Lawrence M. Breed
Lawrence (Larry) Moser Breed
|Known for||Scientific Time Sharing Corporation (cofounder)|
|Awards||Grace Murray Hopper Award, 1973|
|Influences||Kenneth E. Iverson|
As an undergraduate at Stanford University in 1961, he created the first computer animation language and system and used it at Stanford football half-times to coordinate images produced by a 100 ft-by-100 ft array of rooters holding up colored cards.
As a graduate student at Stanford, he corresponded with APL's inventor, Ken Iverson, to correct the formal description of the IBM System/360 which used Iverson's notation. After receiving his M.S. from Stanford in 1965, under academic supervisor Niklaus Wirth, he joined Iverson's group at IBM's Thomas J. Watson Research Center in Yorktown Heights, New York, where he created the first implementation of APL, with Philip S. Abrams, on a mainframe computer, an IBM 7090, in 1965.
Breed was the 1973 recipient (with Dick Lathwell and Roger Moore) of the Grace Murray Hopper Award from the Association for Computing Machinery "for their work in the design and implementation of APL\360, setting new standards in simplicity, efficiency, reliability and response time for interactive systems."
With Dan Dyer and others he co-founded Scientific Time Sharing Corporation in 1969, where he led the development of the APL PLUS time-sharing system. While there, in 1972, he and Francis Bates III wrote one of the world's first worldwide email systems, named Mailbox.
Breed rejoined IBM in 1977. He helped develop the International Organization for Standardization (ISO) APL standard, then joined IBM efforts to port Berkeley Software Distribution (BSD) Unix onto IBM platforms. He worked on compilers for the programming language C, floating-point arithmetic standardization, and radix conversion, until retiring in 1992.
Breed became a significant contributor to the Burning Man festival, under the playa name of Ember. He conceived and built the first trash fence to capture windborne debris; created the spiraling, flaming sculpture "Chaotick"; built artistic bicycle light effects; edited and proofread the Black Rock Gazette newspaper, a role in which he continues as a co-founder and director of its successor the Black Rock Beacon, and other Burning Man materials; as an Earth Guardian, promoted the "Leave No Trace" ethos, particularly in post-event cleanup.
In 1973 and 1974 he took first place, with co-solver Donna Breed, in the Dictionary Rally.
Gray-B-Gone and Evapotrons
Associated with his Burning Man activities, Breed devised the Gray-B-Gon, an evaporator for graywater disposal, and through Bay Area workshops directed construction, by Burning Man campers, of over 100 units, as of 2012.
