His works depict scenes from hunting, racing and other sporting events, as well as animal still-lifes.
This likely involves some confusion resulting from his employment with the King of Hanover, who was a member of the British royal family, as there appears to be no evidence that his parents were ever there or that he was adopted.
His father was John Laporte, a noted watercolorist and etcher of Huguenot descent, who was also his teacher.
Later, he was one of the founding members of the Royal Society of British Artists and was a regular contributor to their exhibitions at the Suffolk Street Gallery.
