Industrial chemist Leo Baekeland is remembered as The Father of the Plastics Industry for creating Bakelite, the first synthetic plastic of the world, thus marking the beginning of the Polymer Age. His many inventions include Velox, a special photographic paper, the rights of which he sold to George Eastman.
Ilya Prigogine was a physical chemist remembered for his work on irreversibility, complex systems, and dissipative structures. A respected member of several scientific organizations, Prigogine was honored with the Francqui Prize in 1955. In 1976, he won the Rumford Medal for his work concerning irreversible thermodynamics. His work on irreversible thermodynamics earned him the Nobel Prize in Chemistry in 1977.

Belgian physician and chemist Jan Baptista van Helmont often considered the founder of pneumatic chemistry, is also said to have used the word “gas” for the first time in the scientific world. He is also said to have been the first to identify gas sylvestre, which later came to be known as carbon dioxide.

Belgian chemist Ernest Solvay began working in his family’s salt-making business soon after finishing school, as his condition of acute pleurisy prevented him from studying any further. He is remembered for developing the ammonia-soda process that produces soda ash, which is crucial to the glass and soap industries.

Known for his independent work on olefin metathesis, in which catalysts create and break double carbon bonds of organic molecules, Yves Chauvin played a significant role in the advancement of the green chemistry and helped to develop many new products like advanced plastics, fuel additives, and pharmaceuticals. For this role, he was co-awarded the 2005 Nobel Prize in Chemistry.
