Waldemar Haffkine, born on 15 March 1860, was a bacteriologist from the Russian Empire. He emigrated and worked at the Pasteur Institute in Paris, where he developed an anti-cholera vaccine that he tried out successfully in India. He is recognized as the first microbiologist who developed and used vaccines against cholera and bubonic plague. He tested the vaccines on himself. Lord Joseph Lister named him "a saviour of humanity".
He was appointed Companion of the Order of the Indian Empire (CIE) in Queen Victoria's 1897 Diamond Jubilee Honours. The Jewish Chronicle of that time noted "a Ukraine Jew, trained in the schools of European science, saves the lives of Hindus and Mohammedans and is decorated by the descendant of William the Conqueror and Alfred the Great."[3]
In his final years Haffkine became more religious, becoming an advocate and philanthropist for Orthodox Jewish causes and a supporter of Zionism.
