Incidentally, "Jupiter" comes from the Greek Zeus, which sounded kinda like Zeiss. Creative, comrades!
Although, "Helios" is the Greek name for the Roman Apollo, god of the sun. The Zeiss Sonnar was such-named because it was very bright and fast for its day (which was the early 1930's). However the Helios-44-2 is not a Sonnar, the Jupiter-3 is.
