Manson has been called the “father of modern tropical medicine”. He had vast experience of disease in the Tropics and himself made many valuable contributions to the knowledge of this subject. He described tinea nigra and tinea imbricata, found fllaria in elephantiasis and discovered Filaria hominis. In 1898 he founded the London School of Tropical Medicine. The 16th edition of his book, edited by P. H. Manson-Bahr, appeared in 1966.
