Who knows about Basil Clarke, PR pioneer and war correspondent?

Can anyone out there help Richard Evans with his biography of Sir Basil Clarke , the public relations pioneer who was previously a celebrated journalist? The Wikipedia entry for Clarke, pictured here, shows how interesting a figure he was during his lifetime from 1879 until 1947. He worked for the Manchester Guardian , as sub-editor and then reporter, for six years from 1904. At the outbreak of the first world war, he was a frontline correspondent for the Daily Mail before joining Reuters and the Press Association . Later, he became editor of the Sheffield Independent until, in 1924, he set up one of the first PR agencies and wrote a book that's regarded as the first British code of ethics for public relations.
