Aleksander Gieysztor and Gerard Labuda for the 100th anniversary of two great historians’ birthdays (1916–2016)

Gerard Labuda and Aleksander Gieysztor were among the most distinguished Polish historians. Their impact on the development of Polish Medieval studies has been tremendous as testified by a large group of their disciples who continue the research commenced by the Poznań and Warsaw historians. Two polish historians and friends, both born in 1916, were among the most eminent medievalists in Poland in the 20th century. Their academic debut came in the years preceding the outbreak of WWII, while their careers progressed brilliantly in the years following the end of the war. For several decades, they marked their academic presence as the authors of great works, and they held the most prominent offi ces in academic life in Poland and in the international arena. They took an active part in the process of political transition, leading to Poland regaining full sovereignty in 1989, and they approved of its evolutionary mode. They were unquestionable moral authorities for scholarly circles and beacons in public activities. Aleksander Gieysztor died in 1999, followed another eleven years later by Gerard Labuda (2010), who remained active until his last days. The 100th anniversary of their birthdays reminds historical circles, first and foremost, albeit not only, of Warsaw and Poznań, about their academic and public achievements.
