American actor who played Doctor Nichols, the Plexicorp manager to whom Scotty and McCoy hand the formula for transparent aluminium, in Star Trek IV: The Voyage Home.
Alex Henteloff is an American character actor with decades of television guest roles, including a recurring part in Barney Miller.
In Star Trek IV: The Voyage Home (1986) he played Doctor Nichols, plant manager at Plexicorp in San Francisco. Scotty, posing as a visiting professor from Edinburgh with McCoy as his assistant, needs sheets of acrylic to build a whale tank and offers in exchange the molecular structure of transparent aluminium.
Nichols watches in amazement as Scotty, after failing to talk to the computer, types the formula into a Macintosh. McCoy worries about changing history, and Scotty suggests that Nichols may have been the inventor all along.
