Who is Rudolf Weigl?

Rudolf Weigl is a Polish biologist, doctor, and inventor credited with developing the first successful vaccination for epidemic typhus. He was a nominee for the Nobel Prize in Medicine each year in the 1930s.

Weigl helped during the Holocaust to save the lives of many Jews by creating the typhus vaccine and offering shelter to people suffering under the Nazi Germans in Poland.

He was recognized as a Righteous Among the Nations in 2003 for his contributions. Rudolf Weigl’s Net Worth was estimated to be $1 Million according to 2024 Update.

Rudolf Weigl’s Net Worth, Professional Career & World War Contributions

Weigl joined the Austro-Hungarian army’s medical staff when World War I broke out in 1914 and immediately began investigating the origins of typhoid disease.

From 1918 until 1920, Weigl oversaw the Laboratory for the Study of Spotted Typhus at a military hospital in Przemyl. He joined the Polish army’s sanitary committee that same year (1919). Through study and trial and error, he eventually created a vaccine.

Weigl maintained his employment at an Lwów facility after the German invasion of Poland in 1939. He was able to ramp up the manufacturing of his typhus vaccine there.

For the next four years, he worked at Lwów on developing a vaccine against spotted fever. He oversaw operations at Lwów’s Institute for Typhus and Virus Research.

 Although Weigl’s spotted fever vaccine didn’t completely protect its recipients from the disease, it significantly reduced their symptoms.

World War II saw Weigl’s studies come to the notice of the Nazis when Germany occupied Poland. During their occupation of Lwów, he was forced to convert his Institute into a typhus vaccine factory.

Weigl brought several Jewish associates and friends to work in the factory on board. Approximately 2,000 Polish intellectuals, Jews, and members of the Polish underground were employed and protected by Weigl.

Some of the workers he employed helped him with his typhus studies and lice experiments. Many of his Jewish friends primarily contributed to the lice-growing process in exchange for food, shelter, and Vaccine doses once it was ready.

The ghettos of Lwów and Warsaw, as well as other concentration camps and even some Gestapo prisons, received his vaccines through clandestine channels. 

The number of lives that Weigl saved from the Nazis is estimated to be around 5 000. According to Forbes Update, the Famous Polish Biologist Rudolf Weigl’s Net Worth was estimated to be $1 Million by his death.

Rudolf Weigl Vaccine Development; How did he save thousands of Jew’s Life?

Weigl developed a method to produce a typhus vaccine in 1930 by growing infected lice and crushing them into a vaccine paste, building on Charles Nicolle’s 1909 discovery that lice were the vector of epidemic typhus and on the work done on a vaccine for the closely related Rocky Mountain spotted fever.

He found that Rickettsia prowazeki, the human typhus pathogen, could be extracted from the stomachs of infected lice and used to create a vaccine.

He developed this first vaccine version in 1918 and began experimenting with guinea pigs and human volunteers.

Over the years, he honed this method, and in 1933, he conducted extensive experiments to produce bacteria and experiment with the lice using a micro-infection strategy. The process had four main phases:

A healthy head of lice takes roughly 12 days to grow;

Inoculation with typhus;

Extending the period of growth by five more days;

Making a paste by extracting the midguts of the lice and crushing them (which was the Vaccine).

To cultivate lice successfully, one needed to give them human blood. Around 1933, he expanded his testing to humans, feeding the lice human blood by letting them suck human legs through a screen. Initially, he used guinea pigs to see if his method would work.

This could cause typhus during the latter phase when the lice were infected. He solved this issue by immunizing the human “injectees,” ultimately saving their lives (though some did develop the disease).

Weigl and his wife, Zofia, were pioneers in feeding lice. He fell ill, but he eventually got better.

Belgian missionaries in China used his vaccination for the first time on a large scale between 1936 and 1943. Africa was not left out of the vaccination program for long.

It was difficult and risky to mass produce the Vaccine. The Cox vaccine, originally derived from egg yolk, is one example of a safer, cheaper vaccination developed over time.

Rudolf Weigl Legacy & Death

The General Microbiology Institute of Jagiellonian University named Rudolf Weigl, its director, and the University of Pozna’s medical school made him the biology department head. Although he left the vaccine business in 1951, production continued for a while.

At 73, Weigl passed away on August 11, 1957, in the Polish ski town of Zakopane. The famous Kraków cemetery of Rakowicki now has his remains.

Weigl’s Institute was established in the typhus research department at Lwów University in honor of his contributions to the disease study. The Institute plays a major role in Andrzej uawski’s The Third Part of the Night (1971).
