Ter, Lower Case ‘t’
When Richard Nixon resigned in 1974 and Gerald Ford became President, his first press secretary was a man named Jerald terHorst. TerHorst served for exactly one month before himself resigning after Ford’s apparently unexpected pardon of Nixon. TerHorst found the pardon unconscionable considering Ford’s non-pardon of Vietnam draft-dodgers.
The man’s surname name, terHorst, begins with a lower case ‘t’ unless used at the beginning of a sentence. There’s a surprisingly embittered and childish fight about the proper capitalization and its noteworthiness on Wikipedia.
