Albert A. Michelson
In an episode of the television series "Bonanza" ("Look to the Stars", broadcast March 18, 1962), Ben Cartwright (Lorne Greene) helps the 16-year-old Michelson (portrayed by 25-year-old Douglas Lambert (1936–1986)) obtain an appointment to the U.S. Naval Academy, despite the opposition of the bigoted town schoolteacher (played by William Schallert). "Bonanza" was set in and around Virginia City, Nevada, where Michelson lived with his parents prior to leaving for the Naval Academy. In a voice-over at the end of the episode, Greene mentions Michelson's 1907 Nobel Prize.
Bonanza
Attempts to replace Adam with Little Joe's maternal half-brother Clay (Barry Coe) and Cartwright cousin Will (Guy "Zorro" Williams), were unsuccessful. Creator David Dortort introduced a storyline that would keep the character of Adam in the mix, but with a lighter schedule. During season five Adam falls for a widow with a young daughter, while making Will Cartwright a central figure. Roberts decided to stay an additional season, so the scripts were quickly revised by having Adam's fiancée and her daughter depart the series prematurely with Guy Williams' Will, with whom she'd fallen in love. It was Landon, not Roberts, who objected to the infusion of any new Cartwrights. After Roberts did leave the following year, it was eventually mentioned that Adam had gone "to sea", and in the later movies he had emigrated to Australia and had a son Adam 'A.C.' Cartwright, Jr. In mid 1972, the series producers considered inviting Roberts back in the wake of Dan Blocker's death: "One suggestion was to return Pernell Roberts, who had played another Cartwright son when "Bonanza" first premiered on NBC fourteen years ago. We only considered that briefly, [producer Richard Collins says] Some people felt it was a logical step—the oldest son returning at a time of family need—but most of us didn't think it would work.'
