Lord Haw-Haw was a nickname applied to the Irish-American William Joyce, who broadcast Nazi propaganda to Britain from Germany
during the Second World War. The broadcasts opened with "Germany calling, Germany calling", spoken in an affected upper-class English accent. The same nickname
was also applied to some other broadcasters of English-language propaganda from Germany, but it is Joyce with whom the name is now overwhelmingly identified.
There are various theories about its origin.
