Alfred Swaine Taylor (1806-1880), was one of the foremost toxicologists of the 19th century, often appearing in court providing medical evidence in cases of suspected poisonings. Following the publication of his book 'Elements of Medical Jurisprudence', Taylor was appointed Profesor of Medical Jurisprudence at Guy's Hospital Medical School in London. In addition to his medical career, Taylor is also notable as one of the 'fathers of photography', developing the use of hyposulphate of lime as a fixing element.
