Paul Guldin

(1577 - 1643)

Swiss astronomer and mathematician

Swiss astronomer and mathematician
Swiss mathematician and astronomer celebrated for theorems connecting the geometry of solids to their centroids’ paths.
Swiss astronomer and mathematician, Paul Guldin made lasting contributions to geometric analysis in the early 17th century. He is best known for the Pappus-Guldin theorems, which relate the surface area and volume of solids of revolution to the path of their centroids. Guldin taught at the University of Graz and corresponded with prominent scientists like Galileo Galilei. His investigations extended to calendar reform and the motion of the Earth, reflecting the era’s scientific debates. Though overshadowed by his contemporaries, his theorems remain fundamental in integral calculus. His work bridged classical geometric methods and emerging analytical techniques.

French physician, bacteriologist, and immunologist

French physician bacteriologist and immunologist
French physician, bacteriologist, and immunologist, who pioneered the development of diphtheria antitoxin and helped establish the Pasteur Institute.
Émile Roux began his medical training in Paris and joined Louis Pasteur's laboratory in the 1870s, where he worked on vaccine research. He contributed to the development of the diphtheria antitoxin, which greatly reduced mortality from the disease. In 1887, he co-founded the Pasteur Institute and served as its first director of the medical and vaccination departments. Roux's research extended to rabies vaccination and numerous bacterial pathologies. His leadership advanced immunology and public health practices in France and beyond. He received the Grand Prix of the Académie de Médecine and was revered for his mentorship of future scientists. Roux's work laid foundational principles for modern bacteriology and vaccine development.

Wilhelm Reich

(1897 - 1957)

Ukrainian-Austrian psychotherapist and author

Ukrainian-Austrian psychotherapist and author
Ukrainian-Austrian psychoanalyst and author, noted for his work on character analysis and the controversial orgone energy theory.
A student of Sigmund Freud, Reich pioneered the field of character analysis and developed theories linking emotional health to bodily energy. In the 1930s, he wrote influential works such as Character Analysis and The Mass Psychology of Fascism. Reich's later research on orgone energy and his invention of the orgone accumulator challenged mainstream science. He emigrated to the United States in 1939 and continued his experiments despite professional opposition. Authorities declared his devices fraudulent, leading to his arrest in 1956 for violating an injunction. He died in federal prison in 1957, leaving behind a controversial but enduring legacy. Reich's ideas have inspired both scientific critique and alternative health movements.
