This interview with Kirshner is a good read as well: https://www.aip.org/history-programs/niels-bohr-library/oral... And a reminder that science is not generally moved forward by strokes of brilliance, but by a whole bunch of people grinding at the fuzzy edge until the picture becomes a little more clear.
Great quote. Also unintentionally (I think) humorous, given the manufacturing problem with Hubble referred to in the article was slightly inaccurate grinding of the lens' edges.
