Petr Hájek studied at the faculty of mathematics and physics of the Charles University in Prague.{{Cite web|url=http://www.cs.cas.cz/hajek/|title=Hájek Petr, prof., RNDR., DRSC}} Influenced by Petr Vopěnka, he specialized in set theory and arithmetic, and later also in logic and artificial intelligence.{{cite web |url=http://vit.ad.umel.feec.vutbr.cz/portalZS/ContentPage.aspx?PageID=b97b0db3-8760-44b8-8b8c-2794d505e0d8 |title=VIT - Hájek Petr |accessdate=2015-07-09 |url-status=dead |archiveurl=https://web.archive.org/web/20150710094730/http://vit.ad.umel.feec.vutbr.cz/portalZS/ContentPage.aspx?PageID=b97b0db3-8760-44b8-8b8c-2794d505e0d8 |archivedate=2015-07-10 }} He contributed to establishing the mathematical fundamentals of fuzzy logic. Following the Velvet Revolution, he was appointed a senior lecturer (1993) and a professor (1997). From 1992 to 2000 he held the position of chairman of the Institute of Computer Science at the Academy of Sciences of the Czech Republic. From 1996 to 2003 he was also president of the Kurt Gödel Society.{{cite web | url = http://kgs.logic.at/index.php?id=42 | archive-url = https://web.archive.org/web/20040924120519/http://kgs.logic.at/index.php?id=42 | url-status = dead | archive-date = 2004-09-24 | title = Our Presidents | work = Kurt Gödel Society }}

Later, he graduated from the Academy of Performing Arts in Prague, where he studied the pipe organ under Jiří Reinberger to become an organ player in a church.{{Cite web|url=http://www.radio.cz/cz/rubrika/kaleidoskop/nas-host-matematik-s-hudebnimi-sklony|title = Náš host: Matematik s hudebními sklony|date = 26 May 2007}}
