Due to his place of birth he was known as "Frenchie". He met Minnie in New York where he was working as a dance teacher. Their first son, Manfred, born 1885, died in infancy.
Marx was an excellent pinochle player, a game he taught to his two oldest sons.
Marx became a tailor, although not a very good one. He was a talented cook, often convincing the landlord to delay their rent paytime with a good meal.
In his show An Evening With Groucho, Groucho reminisces about Sam Marx:
Harpo puts the bad tailoring down to the fact that Frenchie never actually took the time to measure a client for a suit, preferring to guess their size. He would then take suits that clients had rejected and travel to New Jersey and sell these door-to-door.
In his last interview, Zeppo joked that his father "was a very bad tailor but he found some people who were so stupid that they would buy his clothes, and so he"d make a few dollars that way for food".
Sam Marx died on May 10, 1933, from complications due to renal failure. He was 73.
