Who was the first American to walk in space?

The first American to walk in space was Ed White. His historic spacewalk took place on June 3, 1965, during the Gemini 4 mission. This achievement marked a significant milestone in the space race and demonstrated the capability for extravehicular activity (EVA), which is critical for future missions, including those involving repairs or assembly in space. Ed White's nearly 23-minute spacewalk involved him using a handheld maneuvering unit, allowing him to move around the spacecraft while experiencing the sensation of weightlessness. His accomplishment showcased not only his skill as an astronaut but also the technological advancements being made by NASA in human space exploration during that era.
