Thomas Herbert Maguire was a painter and lithographer working in London in the middle of the nineteenth century. Maguire specialised in portraits and genre scenes; he was best known for a series of representations of eminent physicians and surgeons, which was commissioned by the College of Surgeons. He was lithographer to Queen Victoria, and exhibited a portrait of her at the Royal Academy in 1855. The National Portrait Gallery, London, has scores of his lithographs.
