Hi all,

Nobel Laureate Harold Urey was both instrumental in
meteorite science with his (and his students)
discoveries, as well as pushing students in new
directions due to disagreements with him. As Urey
studied meteorites, he tended to lean towards a large
(planetary) source for their origin. However, others
disagreed and felt that smaller bodies (asteroids)
were the source of meteorites. Obviously Urey lost
that battle.

While the Miller-Urey experiment is likely the most
influential and memorable contribution Urey made to
science, in essence his work led many to conclude that
he was the first to apply modern science to the study
of the solar system, and the person who pushed the
term cosmochemistry into popular science usage. Urey
was also leader in hte movement to reclassify
meteorites according to chemical criteria rather than
physical looks.

Here is a link to an Accretion Desk article I wrote
about Urey and meteorites for the Meteorite Times:

Happy reading
again.
