Leo Vroman (born April 10, 1915 – died February 22, 2014) was a talented Dutch-American scientist and writer. He was known for his work with blood (a hematologist) and for writing many poems, mostly in Dutch. He was also a skilled illustrator.

A Life of Science and Words

Leo Vroman was born in Gouda, a city in the Netherlands. He was from a Jewish family. He studied biology at Utrecht University.

Fleeing War and Internment

When the Nazis took over the Netherlands on May 10, 1940, Leo had to leave his home. He first went to London. From there, he traveled to the Dutch East Indies (which is now Indonesia). He finished his studies in Batavia.

Later, when the Japanese occupied Indonesia, Leo was captured. He was held in several prisoner-of-war camps. In one camp called Tjimahi, he became friends with other writers, Tjalie Robinson and Rob Nieuwenhuys.

New Life in America

After the war, Leo Vroman moved to the United States. He started working in New York City as a researcher studying blood. His uncle, Isidore Snapper, who was also a doctor and researcher, lived in New York. Leo became an American citizen. He lived in Fort Worth, Texas, until he passed away in 2014 at the age of 98.

Awards and Recognition

In 1946, Leo Vroman's first poems were published in the Netherlands. Over the years, he won almost every major Dutch poetry award. In 1970, Wayne State University in Detroit, Michigan, gave him a special award for his science work.

In 2003, his old high school in Gouda changed its name to de Goudse ScholenGemeenschap Leo Vroman (GSG Leo Vroman). This was a great honor for him. Leo Vroman married Georgine Marie Sanders in September 1947. They had been engaged since May 1940. They had two daughters together.
