Who Was William Montgomery?

William Montgomery was born in Liverpool in 1871. He studied at the University of London and St John's College, Cambridge. He became a minister in the Presbyterian church. But his skills went beyond religious studies. He was also very good with languages and codes.

Joining the Codebreakers

Room 40 was full of brilliant minds. They worked hard to understand hidden messages. These messages could give Britain an advantage in the war. Montgomery's language skills were very useful here.

The Zimmermann Telegram

William Montgomery is most famous for his work on the Zimmermann Telegram. This was a secret message sent by Germany in 1917. It was meant for Mexico.

Impact on World War I
