Childhood and education 
He was a son of John Manson and Elizabeth Livingstone Blaikie, born at Oldmeldrum, eighteen miles north of Aberdeen. His father was manager of the local branch of the British Linen Bank and Laird of Fingask, while his mother was reported to be a distant relation of David Livingstone. He was the second son of a family of three boys and four girls. He obtained the Bachelor of Medicine at the University of Aberdeen in 1865, his Master of Surgery in 1866 and his Medical Doctorate and Doctor of Law in 1866.
Manson traveled to Formosa (now Taiwan) in 1866 as a medical officer to the Chinese Imperial Maritime Customs, where he started a lifelong career in the research of tropical medicine. After 5 years in Formosa (Taiwan), he transferred to Amoy, on the Chinese coast where he worked for another 13 years. From 1883 to 1889, he practised medicine in Hong Kong.
Researching filaria 
He spent his early years researching filaria (a small worm that causes elephantiasis). Manson focused his time on searching for filaria in blood taken from his patients. From this he began to work out the life cycle of filaria and through painstaking observation discovered that the worms were only present in the blood during the night and were absent during the day.
He conducted experiments on his gardener, Hin Lo, who was infected with filaria. He would get mosquitoes to feed on his blood while he slept and then dissect the mosquitoes filled with Hin Lo's blood. "I shall not easily forget the first mosquito I dissected. I tore off its abdomen and succeeded in expressing the blood the stomach contained. Placing this under the microscope, I was gratified to find that, so far from killing the Filaria, the digestive juices of the mosquito seemed to have stimulated it to fresh activity."
Manson observed that filaria only developed as far as an embryo within the human blood and that the mosquito must have a role in the life cycle. Through these early experiments he started to hypothesise about the role of mosquitoes and the spread of disease. Out of this arose the mosquito-malaria theory, which suggested that the agent that causes malaria was also spread by a mosquito. This discovery was one of the most important medical breakthroughs of the time. Under the constant supervision of Manson, Sir Ronald Ross described the full life cycle of the plasmodium inside the female mosquito. Manson's theory was finally proved by Ross in 1898, who won the Nobel Prize in 1902 for this discovery. Manson also demonstrated a new species of Schistosoma (Bilharzia) known as Schistosoma mansoni.
Introduction of Scots cattle to Hong Kong 
He was the first to import cows from his native Scotland to Hong Kong and thus establish a dairy farm in Pok Fu Lam in 1885 and the company Dairy Farm in Hong Kong. He was the founder of the Hong Kong College of Medicine for Chinese, where Sun Yat-sen was one of his first pupils. In 1896, through his contacts at the Foreign Office, Manson managed to secure the release of Sun after he had been kidnapped in London by Chinese officials. Sun went on to become the first President of the Republic of China. In 1911 Hong Kong College of Medicine for Chinese became the University of Hong Kong.
He returned to London in 1889, and in 1897 was appointed Chief Medical Officer to the Colonial Office. It was here that he used his influence to push for the foundation of a School of Tropical Medicine at the Albert Dock Seamen's Hospital. The London School of Hygiene & Tropical Medicine was opened on 2 October 1899. He retired from the Colonial Office in 1912.
Honours and awards 
- Elected to the Royal Society in 1900.
- Knighted KCMG in 1903 and GCMG in 1912.
- Awarded the Fothergill medal in 1902.
- Awarded an honorary Doctorate of Science by the University of Oxford in 1904.
- First president of the Royal Society of Tropical Medicine and Hygiene in 1907.
In 1876, he married Henrietta Isabella Thurbun, with whom he had three sons and one daughter.
His daughter married Philip Heinrich Bahr, one of Manson's pupils at the London School of Tropical medicine. Sir Philip Manson-Bahr CMG DSO MD FRCP (Lond) became a leader in the field of tropical medicine in his own right.
In 1995 Manson's grandson, Dr (Philip Edmund) Clinton Manson-Bahr won the Manson Medal. It is the Royal Society of Tropical Medicine's highest mark of distinction for contributions to tropical medicine, and is awarded triennially.
