Tec 4 Walter Jacob, a statistician in civilian
life, spent about six months in the Newmanry on a special
mission from Washington to study the Fish problem. His con-
tributions in the application of statistical theory to the
work speak for themselves in the research logs.
Capt Herbert Maas spent about two months in the
Newmanry and the Testery as an observer from Arlington Hall
Tec 5 Walter Sharp, a math instructor at Ohio University, also
spent two months in the Newmanry.
The 5202 machine, another Arlington Hall inven-
tion which did electronic counting on film instead of paper
tapes, brought Lt George Dixon and Tec 3 William O'Donnell to
the Newmanry. The walls had first to be knocked down before
the machine could be moved into its room and when it was almost in
operating order, victory came. They stayed on however to test out
the machine on a mock operational basis and have since returned
to the States.
There are two other Americans who should be men-
tioned since they were closely connected with the problem al-
though they did not belong to the Army. They are Mr Albert
Small, a civilian cryptanalyst, who spent some time writing a
Fish report for Washington and Lt Comdr Howard Campaigne of
the US Navy who worked in the Newmanry during its last year.
