Name change: First name of Móric (also Mór, Moriz or Moritz) he was born to a Jewish family with the surname ‘Kohn‘. In 1869 he converted to Catholicism and in 1871 changed his surname to Kaposi (apparently in reference to his home town of Kaposvár). It is reported that the rationalization for the name change was that ‘Kohn’ was a common name carried by hundreds of people of various classes and of different professions and that mistakes were constantly and increasingly made about persons carrying the same name. At Vienna University alone there were five doctors with a similar surname; one even with the same given name Moriz. He was concerned about the possibility that his scientific work would mistakenly be credited to colleagues bearing the same surname. Kaposi explicitly stated that it was for these reasons alone that he wished to change his name.
Kaposi was a very proud and self confident man. He used to add “mihi” to newly described entities, e.g. Xeroderma pigmentosum so as to make absolutely certain that HE was the original author and not somebody else!
Not everybody liked him: ‘On disait de Kaposi qu’il avait pris la fille de Hebra, sa maison, sa chaire et sa clientèle, laissant le reste à son beau-frère Hans Hebra.‘ [It was said of Kaposi that he took Hebra’s daughter, his house, his pulpit, and his clientele, leaving the rest to his brother-in-law Hans Hebra] – William Dubreuilh (1857-1935), first professor and chairman of dermatology in Bordeau
