Star Trek & 1960s Design, 11: O Is for Open

"It is the pervading law of all things organic and inorganic, ...
Of all true manifestations of the head,
Of the heart, of the soul,
That the life is recognizable in its expression,
That form ever follows function."--Louis Sullivan, American architect, 1896

Fold-out book cover, below: Stile Olivetti (Olivetti Style). Designed by Walter Ballmer for the 1961 Kunstgewerbemuseum, Zürich, exhibiton of designs from the Italian firm Olivetti. Olivetti is known for their modernist design of typewriters, office equipment, advertising and later computers.



Above, center: Kirk pounding his fists against the locked bridge doors, from the Star Trek episode "The Naked Time" (1966).
I also think of all those crashes we see on Star Trek blooper reels, when an actor--often Shatner--walked confidently into a door that didn't open. As you may know, the doors were manually operated, not electrically, as we now take for granted.
