expert in the detection of typographic and other
forgeries associated with the Fogg Museum at
Harvard University, Ehrlich was asked to analyze
the typewriter evidence for Alger Hiss's motion
for a new trial. Ehrlich filed an affidavit
with photographs showing clear differences in
typefaces between the Woodstock machine #230,099
and the machine which typed the "Hiss Standards,"
the personal documents acknowledged to have
been typed on the Hiss's typewriter in the 1930s.
She also said that using the standards applied
by the FBI document examiner, Ramos
Feehan, at trial, one could not tell
the difference between the typing produced by
the machine specially built by the Hiss defense
for the motion for a new trial and the Hiss
Standards -- thus suggesting that forgery by
typewriter was possible.
