The IBM Scientific Computation Forums held in 1940, 1946, 1947, 1948, 1949, plus another three in the 1950s, were devoted to discussion of methods for solving scientific problems using IBM punched card equipment. The people who attended these gatherings pushed IBM machines far beyond their intended simple business and tabulating functions, largely due to the press of war, which required massive amounts of computation related to ordnance (trajectory, blast), navigation (lunar and stellar tables), aerodynamics, simulation, and other areas requiring application of higher mathematics, not to mention automatic sequencing and decision making to allow long, complex calculations to run to completion without manual intervention. From this work, modern computing was born.
Proceedings were published for each forum; softcover through 1947, hardcover thereafter. The proceedings of the 1948 conference were published as: Grosch, H.R.J, Editor, Watson Scientific Computing Laboratory, Proceedings, Scientific Computation Forum, International Business Machines Corporation, New York NY, 1948:

Thanks to Herb Grosch for the photo, the page scans, and the identifications (August 2003). Seeber and Murray are not in the photo; they attended only the part of the forum that was held at the SSEC at IBM headquarters in NYC.
Thanks to Ken Frantz of Hayes, VA, for identifying his father, Walter
(January 2006), and to
for identifying his aunt Lydia (April 2006).
And to Jari Salo writes from Helsinki, Finland (May 3, 2011),
That's Leland W. Sprinkle,
the inventor of the Great Stalacpipe Organ, the
largest instrument in the world ( located in Luray, Virginia).
If you don't know the instrument, here's info about it. It is QUITE something:
My colleague Paul Malmström has composed the performed the first ever
original tune for the organ, and I'm writing an article about the organ and
its history. I found your photo and Mr. Sprinkle was identified by Luray's
