Father Henry Cyril Dieckhoff (ru|Генрих Кирилл Дикхофф) (1869-1950) was a Russian Catholic priest and linguist.[1] He was born in Moscow, the son of a Lutheran preacher, but spent much of his youth in Germany, as his mother was Catholic and unable to continue living in Russia.[2] He studied in Berlin and was given Holy Orders without permission from the Russian authorities and therefore first fled to England and then Scotland, where he was welcomed as a brother at the Fort Augustus Abbey in 1891.[2] He gained priesthood six years laters in 1897.[2]
He learnt Scottish Gaelic and did detailed research into the dialect of Glengarry and published a dictionary on the dialects, A Pronouncing Dictionary of Scottish Gaelic.[3] His dictionary was unusual for the time as it included detailed pronunciation information not only on the citation forms but also inflected forms of the entries.
