Dean Benjamin McLaughlin

In 1954, he proposed the theory that there are volcanoes on Mars and that their eruptions change the albedo features called "mare" (The Martian equivalent of Lunar mare). His proposal was partially confirmed in 1971 with the arrival of Mariner 9, which showed that strong winds could move dust around the planet, creating the changes of appearance formerly attributed to some kind of vegetation.

A crater on Mars was named in his honor, as is the crater McLaughlin on the far side of the Moon and the asteroid 2024 McLaughlin. In 2014 NASA scientists announced they had discovered evidence of water in Mars' McLaughlin Crater.
