[Tlhingan-hol] George Sassoon studied Klingon?

[De'vID]

So I came across this recently...
http://en.wikipedia.org/wiki/George_Sassoon
"He was noted for his prodigious linguistic ability, learning
languages which included Serbo-Croat, Hebrew, Aramaic and Klingon"

Wiki vandalism? Or did he really study Klingon (seriously enough to
include it among other languages he studied)?

Was he known as a Klingonist to the community?
