John, Arthur C Clark came up with the idea [allegedly the first person to do so although it seems a very obvious idea and Kepler was born long ago]. But perhaps Rosen was the first one to build a satellite. I noticed the comment and took it to mean that he was in charge of the first actual geostationary satellite.

That is a lot more difficult than noticing that if the moon goes around the earth once a month and a low satellite would take only an hour or two and a sea-going trip Around the World takes 80 days, there should be an orbit which would take exactly one day and would be good for communications and stuff.

That's like me figuring out that coding cellphone signals using Fourier transforms would be a good idea to share spectrum. Easy to think of the idea [even if it had been thought of decades before] but not so easy to actually get a geostationary satellite to work way up there with photovoltaic wings which hadn't been tried before.
