Deletion of Jozef Teodor Mousson

Comment: The only source provided in the article(there are others), which doesn't appear in any libraries I can consult, including worldcat, appears to be https://www.historiamichaloviec.eu/h-michalovce/h-m-publikacie/12-teodor-jozef-mousson?showall=1 this book, which appears to be a serious monograph. That is significant critical attention, so he can pass . His work appears at auction, and if the listed prices http://www.dartesro.sk/?act=autor&id=304&lang=sk example are real, €12,000 to €27,000 is respectable
