Thompson and Capper were homeopathic chemists who, as well as making their own medicines, published books and pamphlets on homeopathy. The company is still going strong today - based in Runcorn, they are a specialist manufacturer of all kinds of tablets, from medicines to kettle descalers, and there is more information about their history on their website.
