American actor, famous as Ralph Malph in Happy Days, who played Kadan, the Quarren doctor rewriting abducted workers' memories, in Voyager's two-part Workforce.
Don Most is an American actor and singer best known as the joker Ralph Malph in the comedy series Happy Days.
He appeared in both parts of the seventh-season Voyager story Workforce as Kadan, a physician at a hospital on Quarra. Kadan runs the scheme at the heart of the plot: aliens are abducted, diagnosed with an invented illness and given new memories so that they will settle contentedly into jobs on the labour-starved planet.
When Tuvok's conditioning starts to fail and a younger doctor grows suspicious, Kadan tries to conceal what he has done, justifying it as a service to Quarra's economy.
