With two copies of the same text helping to eliminate garbles,
Montgomery and de Grey rammed into the cryptogram. De Grey, though
at 30 the younger of the two, had been in Room 40 the longer. Slightly
built, rather handsome, with dark hair and brown eyes and chiseled,
movie-star features, an Eton graduate, he was descended from the
peerage as the grandson of the fifth Baron Walsingham (no relation to Sir
Francis Walsingham). He had worked for the prestigious publishing
house of William Heinemartn for seven years before the war, when he
joined the Royal Naval Air Service. He came to Room 40 in 1915.
Montgomery was 45 at the time of his work on the Zimmermann
telegram. A Liverpool shipowner's son who studied in private schools or
under tutors in England, France, and Germany, he took a bachelor of
divinity degree at Presbyterian College, London. But his health prevented
an active pastorate and he became a member of St. John's College at
Cambridge University
