Dan Jezek was born June 25, 1977 in Prague, behind the Iron Curtain in what was then Communist Czechoslovakia. Dan was the son and only child of two accomplished parents: Jaroslav and Eliska Jezek (Jezkova). Jaroslav made a name for himself as a mathematical genius in his early twenties when he “solved the unsolvable”. Jaroslav came up with a mathematical proof to a theory that had remained an enigma for more than a century. In so doing he developed the early now-established proofs of what is today Universal Algebra. Immediately, the young mathematician won both notoriety and a chair at Charles University where he remained a resident scholar the rest of his life, until his death in February 2011. Dan’s mother Eliska was graduated from Charles University in Prague in 1979 with a doctorate of jurisprudence, a law degree.
In his capacity as a professor of mathematics, Jaroslav was well known throughout mathematical communities at university campuses around the globe. The Bolshevik government in Prague was willing to grant him and his wife and young son permission to travel abroad during summer breaks from Charles University to serve as visiting professor in western universities. Their travels took them to Germany, Canada, Berkeley in California, Vanderbilt in Nashville, Tenn., the University of South Carolina, and the University of Hawaii.
