‘Jack of all trades’ was thought to be coined as a term to reflect a type of individual, as opposed to just one guy, back in the 14th Century. It was originally used more as a compliment to a person who had a broad range of knowledge and skillset – thus being seen as a very handy person to have around!
Later the phrase ‘master of none’ was added, which is what we tend to be more familiar with today. Commentators from around the 16th Century wanted to imply that the person was stretching their talents too thinly.
