Harrison Schmitt

 

(Wikipedia) Harrison Hagan "Jack" Schmitt (born July 3, 1935) is an American geologist, retired NASA astronaut, university professor and former U.S. senator from New Mexico.
In December 1972, as one of the crew on board Apollo 17, Schmitt became the first member of NASA's first scientist-astronaut group to fly in space. As Apollo 17 was the last of the Apollo missions, he also became the twelfth person to set foot on the Moon, and as of 2015, the second-to-last person to step off of the Moon (he boarded the Lunar Module shortly before commander Eugene Cernan).
