Who is this engineer that designed the voyager 1 spacecraft?

Answer 1

The mission plans were drawn up in 1972 and the mission itself launched in 1977. At the time, Gentry Lee was the mission director at JPL where the craft was developed. A number of engineers designed and worked on the craft. John Casani was the project manager for the Voyager project. I am sure NASA sites have that information archived somewhere.
