Scope and Content
Administrative / Biographical History
Born in Hafod, Wales and brought up on the family farm in Pembrokeshire. On leaving school he was apprenticed to a local apothecary but, at the age of nineteen, he went to London where took a post firstly with a chemist in Streatham and then as dispenser to the German Hospital. While at the hospital he learned German and attended lectures at University College London. He then moved to Aberdeen where he qualified in 1867. The following year he went to the Army Medical School at Netley, Hampshire where at the end of the four-month course passed out first on the list.
In 1869 Lewis was posted to India where he investigated cholera. While studying chyluria (the presence of lymphatic fluid in urine), he discovered minute worms in the urine of one particular patient. Subsequently they were identified as Filariidae, but in the meantime the patient disappeared before Lewis could carry out further investigations. In 1872 Lewis found similar worms in a blood sample. When this work was written up Lewis was amazed to discover the original patient setting up the type for its publication by the Government Printing Office in Calcutta. Later he found the mature worm but it had already been discovered independently of him by Joseph Bancroft in Australia. However he discovered and described the first trypanosome, which was named Trypanosoma lewisei after him, in the blood of a mammal. In 1883 he was appointed Assistant Professor of Pathology at Netley where he introduced practical bacteriology to the curriculum. He died of pneumonia three years later, allegedly as a consequence of a laboratory accident.
