Georges Phillipe Trousseau (1 May 1833 – 4 May 1894) was a French physician who became the royal doctor of the Kingdom of Hawaii, and engaged in a variety of agricultural ventures.

[4] President of the board of health and Minister of the Interior Ferdinand W. Hutchinson consulted Trousseau when Kamehameha V became ill, but the king died that December.

Trousseau was a firm believer in the germ theory of disease, and used this knowledge to limit the death toll of the outbreak, compared to previous waves that had devastated the native Hawaiian population.

[2] In November 1873, as Lunalilo's health was failing, Trousseau traveled with the royal court to Kailua-Kona and stayed in the Hulihee Palace.

By January 1874, Trousseau thought the king had a short time to live, so he advised Lunalilo to return to Honolulu and deal with naming a successor.

In 1879 he sold the ranch and 11000 sheep to English merchant Henry Nicholas Greenwell and started a new venture,[2] investing in the Pacific Sugar Mill in Kukuihaele.

Records show him being manager in 1879, but after about three years he sold his shares to William H. Purvis and moved back to Honolulu.

When Father Damien was visiting Honolulu from Kalawao in the leper colony at Kalaupapa on the island of Molokaʻi early in 1885, Trousseau diagnosed that the future saint had contracted the disease.

He purchased about 1,000 acres (400 ha) from the Lunalilo estate in Kaimuki just north of Diamond Head, and started raising ostriches.

In the Blount Report, Trousseau accused the descendants of American missions of conspiring with John L. Stevens in the overthrow.

His father was worried to death with his dissoluteness and foolish extravagance, and had to pay enormous sums of money to extricate him from his disgraceful orgies and gambling complications.

[18]Trousseau admitted he left Paris penniless after losing his money on speculations, but said Sims sensationalized the story.

In July 1893 he resigned from the board of health, protesting that the strict segregation policy (which he had supported about 20 years earlier) was no longer scientifically necessary.
