Martin Waller worked for The Times since 1988 and for more than a decade was its waspish City diary editor. He wrote the Tempus column, analysing corporate news and attempting to give investment advice. Waller currently tweets and writes a blog entitled 'Tom Paine's Bones'. The blog is described as "observations by a fifty-something financial journalist on business, morality, the morality of business and things that make me really angry". The blog has also reflected his interest in history, music, mainly jazz and rock, religion and science fiction.
