Leopold Halpern 1925 2006
physicist, humanitarian, environmentalist, naturalist, world traveler, friend
- Extended scientific obituary by James Overduin and Hans Plendl,
published on-line at:
http://arxiv.org/abs/gr-qc/0608129
and eventually in the
Proceedings of
the Eleventh Marcel Grossmann Meeting on General Relativity.
- Newspaper obituary written by friends Katie Kirwin and Gabriele Plendl in
Tallahasee, FL
where Leopold spent his final days with people who truly loved him:
Leopold Halpern 1925-2006 [htm, pdf,
txt].
A poorly formatted version of this appears as an on-line obituary [June 8, 2006]
at
The Tallahassee Democrat
with an on-line "Guest Book" message board available till June 8, 2007.
- A memorial service was held Friday September 1,
2006 at Wakulla Springs
Donations in memory of Leopold were to be made (on-line or by mail) to the
Big Bend
Hospice, 1723 Mahan Center Blvd, Tallahassee, FL 32308-5428
- A
brief paragraph mentions a canoe ride at Wakulla Springs with Graham
Farmelo just a few months before Leopold's death. Farmelo was researching
his
biography of Dirac. Wakulla Springs was a favorite place of his. bob did
two such canoe events with Leopold and Dirac, among the alligators and water
snakes.

Received his Ph.D. from the
University of Vienna, Austria with a thesis on experimental
solid state physics 1952, won a Fulbright grant which he spent
at R.P.I. 1952-1953. Began an advanced study of theoretical
physics after which he became assistant of E. Schroedinger, then
spent years of research at CERN, UNC, Copenhagen, Stockholm,
Paris P.A.M., Dirac at FSU, the spent 1986-1988 at JPL of
Caltech, returning to FSU 1988. His research interests are in
the theory of Gravitation and its relations to quantum and
Elementary Particle Physics. |

Ani and I last saw Leopold at the GP-B launch at Vandenberg Air Force Base
(California) in April, 2004 and before that kept
him company while he was eating some corn-on-the-cob late one evening sitting on
a wall on the beach front street in Rio at MG10, July 2003. He will be sorely
missed as the grandfather figure of the University of Rome relativistic
astrophysics group G9 of
Remo Ruffini, who
connected us to him.

Philosophy of Science Portal: Paul Dirac...new book
by Graham Famelo
Sep 16, 2009 –
I devoted a lot of time tracking down Dirac’s surviving friends, people who knew him very well. The most important one I found was his last great friend, Leopold Halpern, an expert on relativity who slept in the open air, refused to wash with soap, and liked to slice open baked potatoes with a karate chop. A few years ago, when Halpern was at death’s door with prostate cancer, he flew across the country to Florida, where Dirac spent the latter part of his life, just so he could row me up Wakulla Springs. He and Dirac used to go rowing every weekend. That was a special trip for me: Even now I’m looking at my arm and there are goose bumps. He showed me places where they talked, even where they went skinny dipping. Two and a half months later, Halpern died.
