WHo did the first step on the moon?

It was probably a March, 1969 meeting between Deke Slayton, Bob Gilruth, George Low, and Chris Kraft that determined that Neil Armstrong would be the first person on the moon. It was decided that Armstrong would be the first out because NASA management saw Armstrong as a person who did not have a large ego. A press conference held on April 14, 1969 gave the design of the LM cabin as the reason for Armstrong being first. The hatch opened inwards and to the right, making it difficult for the lunar module pilot, on the right-hand side, to egress first. At the time of their meeting, the four did not know about the hatch issue, and the first knowledge of the meeting outside the four came when Kraft wrote his 2001 autobiography.
