[1] He was born on the day of Saint Blaise as the oldest son to a respectable family of Prague stonemasons (his grandfather Antonio Aichel moved from Cadempino to Prague in the 1630s) and was baptized in the St. Vitus Cathedral as Johann Blasius Aichel.
After his journey through Austria he arrived in Rome, where he had the possibility to meet with the work of Francesco Borromini.
They had four children, but all three sons died from tuberculosis at an early age; the only child left was Anna Veronika (born 1713).
Santini Aichel died at 46, having built over 100 buildings in his twenty-year career, but leaving some unfinished.
Although he had become a well-regarded architect to Bohemia's greatest noble families and monastic orders, his original, eclectic style had few successors or imitators.
