He Was a Good-Natured and Devoted Family Man
Karl had six children by his wife Jenny, and like many a father he came up with nicknames for them. Their eldest daughter, also named Jenny, he called Qui Qui. Daughter Laura was Kakadu and her sister Eleanor was Tussy. (Marx himself was known among family and friends as Mohr — the Moor — no doubt due to his swarthy complexion. In letters Marx sometimes signed himself as Old Nick, a name often applied to the devil.)
