The Philip Harris Ltd firm was a British laboratory supply company, well known to all science teachers in the UK and world-wide as one of the most important suppliers for the peculiar needs of schools. The company was originally based in Digbeth, Birmingham and was established by Thomas Ellis, a surgeon, in 1817. Philip Harris joined Ellis in 1825. They started manufacturing medicines in 1866, adding to their sales of chemist and surgical products: the company traded in Bullring, Birmingham, until 1889.
