In 1958, SpaceLabs was founded by scientists Ben Ettelson and James A Reeves who developed cardiac monitoring and telemetry systems for NASA. These systems were used to monitor astronautsﾒ vital signs in the early Gemini and the following Apollo space missions. During the 1960s, Spacelabs continued its relationship with NASA culminating in Neil Armstrong wearing Spacelabs medical telemetry for the first moon landing in 1969.
