Bart Bok
Bartholomeus Jan Bart Bok was a Dutchborn American astronomer, teacher, and lecturer. He is best known for his work on the structure and evolution of the Milky Way galaxy, and for the discovery of Bok globules, which are small, densely dark clouds of interstellar gas and dust that can be seen silhouetted against brighter backgrounds. Bok suggested that these globules may be in the process of contracting, before forming into stars.
Bok was born in the small Dutch town of Hoorn, north of Amsterdam, to Jan Bok, who was a sergeantmajor in the Dutch army, and Gesina Annetta Bok, but he spent a good deal of his childhood with his grandparents in the town of Haarlem, where he attended primary school. He attended high school in The Hague, excelling at mathematics and science, and he also told the story that this was where he met a Scoutmaster who introduced him to the night sky while on camping trips away from the city lights. After completing high school, he went on to study astronomy at Leiden and Groningen Universities.
