Prof. Davidovitz is a PhD chemist in France who was researching non-flammable polymer alternatives. He discovered a way to make synthetic stone, by taking loose materials, and adding a catalyst, becoming a solid rock. After his discovery he became curious about the Egyptian pyramids and art objects, and realized they had discovered the same formula thousands of years ago. Imagine a plastic not made out of oil? He has built a company around his discoveries, and his writings on ancient chemistry and materials science are fascinating.
Niklaus Wirth is one of the greatest language inventors of all time. He created Pascal, Modula-2, and Oberon, among others. A professor from the Swiss Federal Institute of Technology, his mathematical precision and brevity are inspiration to all.
A pioneer in Operations Research, Mr. Beer wrote extensively on cybernetics and information theory, and how the organization of all complex systems is similar. For example, the roads leading to a city resemble the structure of the veins on a leaf. Who else on planet earth predicted in the 60's that software would be the dominant thing? He called it the "software milieu" and predicted it all decades before anyone else. He worked with Fernando Flores on the administration of Chile under Salvador Allende before his assassination. The fact that people who tried to use his scientific principles got bumped off might explain part of his obscurity.
C. Northcote Parkinson was one of the greatest geniuses of all time. He created an entire field: the study of bureaucracy. His humorous writings were popular in the 50's, and his observations on human nature when inside an organization, are still relevant today.
A masterpiece from one of the great doctors of all time. He was the personal physician to Greta Garbo and many movie stars, but also to my grandmother who lived until 103. Spoiler alert: eat a lot of zucchini.
