Feierabend watchers may find this interesting. There was a family of printers in the 1500's in Frankfurt, Germany, named Sigismund, Hieronymus and Johann Feierabend. Johann was a young cousin of Sigismund, I don't know the relationship of Hieronymus. There was also a M. Feierabend that worked with them as an illustrator. According to the Univ of Utrecht library that has a file on European printers, at various points in their lives these printers spelled their names Feyerabend, Feierabent, Feirabend, Feierabent, Feyerabendt, Feyerabendius, Feyerabendiana, Feyeryabend, Feyerabent, Feyerabendt, Feyerabendus, Feyrabend, Feyrabent. Even Sigismund's first name is spelled Sigmund, Sigismundis, Sygmund and Sigismundus. Sigismund is very famous for publishing the first childrens book and the "Book of Trades" in 1568 among other things. The famous engraver Jost Amman worked as Feierabend's illustrator most of his life. Also interesting is fact that Sigismund was Jewish and married the daughter of a rabbi. I suspect he converted to Lutheranism later because he published Martin Luther's German Bible translation. I can't find any record that they had children. Johann kept the printing business going for 8 years after Sigismund died (1528-1590) but he died in 1599 at age of 26 and there is no record the business continued. Anyone have any more facts on the printers?
Another fact I learned is that the 20th century philosopher Paul Feyerabend said in his autobiography "Killing Time" that his grandfather had changed the family spelling from Feierabend to Feyerabend because he didn't like the literal translation of Feierabend which means end of the day or quitting time. Anyone know if artist Erich Feyerabend (born 1889) is related. I suspect all these spellings come from a common source but I'm not smart enough to track it down. Ernie
