Tributes from former colleagues
Former colleagues have been paying tribute across social media, passing on their condolences to his wife, Susan Grice, with whom he formed Grice Chapman Publishing after retiring from the FT Group.
Helen Elliott, founder and chief executive of titles such as American in Britain and International HR Adviser, wrote a moving letter to FT Adviser.
She had been one of the original staff members brought in by Chapman as the launch team for Financial Adviser.
Elliot said: "I was one of the original members of staff working on Financial Adviser's launch, having been taken on as a secretary and almost immediately being promoted by Colin to sales, which is what I wanted to do.
"I worked with Colin and Nigel Pullman, and a handful of staff in a tiny office in Fetter Lane, before they found the offices in Charterhouse Street.
"I have so many fond memories of my time, and everyone who worked on the launch of the magazine in 1987, as we had a great team and all had a lot of fun."
She added: "Colin was such a lovely man, with a big smile, and was a real help to me and my career, that resulted in me running my own company publishing magazines."
Andrew Michael, an independent editor and publisher, wrote: "Sad news. I did two stints on FA in the early 90s. One on the news desk and one as features editor with the likes of Lawrence Gosling, Bruce Wraight, Kevin O'Donnell, Dominic Rushe (with whom I regularly used to get in lots of trouble) and many others.
"Both experiences were an absolute hoot that helped set me on the way for my first magazine editor's job."
Former Financial Adviser editor-in-chief Kevin O'Donnell, now editor of Financial Planning Today, wrote: "Very sad news. Colin was an excellent journalist and a great character.
"I think I was one of the last people to be interviewed by Colin for a job on Financial Adviser before he left for TV land.
"I think he liked me because I got the job. He fought for FA when others doubted its future and he had a major influence on personal finance journalism in the UK. One of a kind."
Emma-Ann Hughes added: "He was committed to quality journalism that uncovers, interprets, analyses, and strives to give meaning to what is going on in the world."
Broad career
Chapman had enjoyed a broad and fulfilling career, serving as foreign editor of the London Sunday Times, becoming a respected economics correspondent for the BBC, before making his move to Australia where he eventually became a citizen.
