Carl Koppeschaar

Carl Koppeschaar studied astronomy and physics before dedicating himself to science writing. In his pursuit of the shadow of the Moon during total solar eclipses, he traveled to the most exotic places on Earth. The only place left to visit was the Moon, where he researched and wrote the Moon Handbook.

When not observing, doing research on influenza or the epidemiology of infectious diseases and zoonoses , number theory, or science writing, Carl may be found on golf links or hockey fields, trying to launch various projectiles into Low Earth Orbit.

On February 1, 2000 minor planet 7973 Koppeschaar in our solar system was named after him. On August 1, 2001 one of Uncle Scrooge's money entrepôts fell under the blows of the demolition ball for the erection of a statue for the 'inventor of the Moon Dial'.

Carl lives in the centuries-old city of Haarlem, The Netherlands.
