I believe there were several others:
Peter Hyon was a US Army captain and his sister Alice Hyon
was a US Army WAC - both served in Korea (194?-????). USAF 6004 AIIS and
CIC's Donald Nichols, married to a Korean, spoke Korean fairly well.
The 24th ID commander, Gen. William Dean, spoke a little bit of Korean. Some of
the KMAG officers, including Capt. James Hausman, spoke Korean. In addition,
there were several Korean-speaking American
missionaries in Korea.

The following text is lifted from the National Cryptologic Museum's site
as it turns out, it is not the whole story, just an interesting part
The Language Problem
At the time the war began, only two Korean linguists were available to the
Army Security Agency, Youn P. Kim and Richard Chun, both assigned to the Army
Language School in Monterey, California. Y.P. Kim was from California, the son
of Korean immigrants, while "Dick" Chun had grown up in Hawaii. Both had
served in World War II and had been hired by ASA initially because of their
Japanese language abilities.
