Information about Preston C. Hammer, assembled by Jonathan Rees in
late 2012.
Photograph (taken in 1970)
Why did I do this? I met Hammer around 1976 and was impressed by his
outspoken, eccentric manner. In 2012, when cleaning out a file
cabinet, I came across some reprints he gave me, and realized I had a
few things in common with him. I got to wondering what his story was
and spent a day trawling the web for information about him.
I contacted two family members to see if they had any photos or
additional information to share, but received no reply.
I was thinking of creating a Wikipedia page, but this is painful given
Wikipedia's strict policy on thirdparty sources.

1951: was at Los Alamos
(Parter)

(Note: The first storedprogram computer at Los Alamos was the MANIAC,
which didn't come on line until March 1952. I've found no evidence
that Hammer programmed it. His computation experience from 1947 to
1951 seems to have been with the
IBM CPC and its predecessor(s); see
Akera's book. I can't tell whether Hammer was associated with Los Alamos
after 1951. Parter says "the development of computation at Los Alamos
was placed in another group during the summer of 1951" and that Wisconsin
"lured" Hammer away from Los Alamos.)

Biography

During his long academic career, lasting 49 years, he has
been with the
University of Michigan,
Oregon State College,
University of Wisconsin,
Pennsylvania State University, and
[Grand Valley State Colleges].
He has also worked for
extended periods for the Lockheed Aircraft Corporation and the
Los Alamos Scientific Laboratory. ...
(From his
obit, by Parter)

Oral history  Ted Taylor 195053  fission bomb?  CPC
"The head of the computer group was Preston Hammer."

Oral history  Roger B. Lazarus  1950s
"I thought that Carson Mark relieved Preston Hammer from his post as
head
of the computing group since they had a personal conflict."

Oral history  Cuthbert C. Hurd 1950s
"And there's one prior name who was involved  Preston Hammer  and
a tall Ph.D. who wore glasses, became involved in an altercation of
some kind and they both left."

Oral history  Mary Ellen Rudin Wisconsin period

Oral history  Enders Robinson Wisconsin 1958

"At Los Alamos in the '50s someone would get an idea and go down the
hall and get Preston Hammer to put it on the computer and six weeks
later you get printouts and find out whether the guess was right."
(see here)

Preston Hammer was a member of the Math Department Faculty at the
University of Wisconsin from 19521964.
[conflicts with Wisconsin's web site which says 1962]
He later became Chairman of
the Computer Science Department at The Pennsylvania State
University. Preston Hammer returned to the University of Wisconsin,
where he served as Chairman of the Numerical Department; he also spent
a year as a Visiting Professor at the University of San
Diego [196263]. Mr. Hammer was also a student at the University of
Wisconsin [nope],
where he was a member of Pi Mu Epsilon fraternity [national
mathematics honor society].
(From a
LinkedIn profile... several errors here)

"Coffman replaced Bruce H. Barnes, who served as acting in the
absence of Preston C. Hammer, computer science director for seven
years. Hammer, on sabbatical Fall and Winter terms [197273], was eased out of
his job as it passed from one acting director to another."
(see here, June 1 1973)

"Professors see trouble in department shakeup"
The Daily Collegian, 17 January 1973.
"Penn State is accredited with having
one of the best, if not the best, computer
science departments in the nation. It
developed, largely through the efforts of
Hammer, a highly sophisticated undergraduate degree program which
enables students to find work with a
baccalaureate degree."
(see here)

24 Feb 1972, Daily Collegian, Penn State, 'Preston C. Hammer
will speak on 'Creativity" at 8 p.m. Thursday in
202 Burrowes.'
