Glass, Montague: The Competitive Nephew. v1. 22 Jul 2013
 

Montague Glass (born Marsden) (1877–1934) was an English-born United States dramatist and short story writer.
He was brought to America while very young and began his career by contributing to various magazines. All his successful plays were collaborations, and many of them were based on his stories about a pair of comic Jewish business partners: Potash and Perlmutter (1913), written with Charles Klein; Abe and Mawruss (1915), written with Roi Cooper Megrue; and four with Jules Eckert Goodman: Business before Pleasure (1917), His Honor Abe Potash (1919), Partners Again (1922), and Potash and Perlmutter, Detectives (1926). Although several of his other plays received favorable notices, they had short runs.

"That's the way it goes," Sam Zaretsky cried bitterly. "You raise a couple of young fellers up in your business, Max, and so soon they know all you could teach 'em they turn around and go to work and do you every time."
