Seen on the Belgian 2000 Franc note from 1994 to 2001, architect Victor Horta is most famed for his biomorphic details at Hotel Tassel, which he completed in 1894 and is often recognized as the first instance of Art Nouveau in architecture.
Most widely known for the tower that bears his name, Eiffel was an acclaimed architect and engineer, designing many bridges and buildings in the late 1800s and early 1900s. He was featured on the 200 Franc note from 1996 to 2002.
Balthasar Neumann (Germany)
18th Century Baroque architect Neumann was featured on the German 50 mark note from 1991-2002 alongside one of his greatest achievements, the impressively lavish Würzburg Residence.
Gian Lorenzo Bernini (Italy)
Arguably the greatest of all the Baroque artists, Bernini’s sculptures and buildings can still be seen today throughout Italy, notably in his colonnade design for St. Peter’s Square. Bernini adorned the 50,000 lira note from 1985–2002.
Francesco Borromini (Switzerland)
Rival to Bernini, Borromini designed some of Rome’s most dramatic churches, San Carlo alle Quattro Fontane and Sant'Ivo alla Sapienza. He was featured on the Swiss 100 franc note from 1976–2000, though not without some controversy, as his hometown of Ticino, while now Swiss territory, was considered part of Italy during Borromini’s lifetime.
Jože Plečnik (Slovenia)
From 1992 to 2007 Secessionist architect Plečnik’s portrait could be seen on the 500 tolar note, recognizing his contributions to the architecture of Ljubljana, including the iconic Triple Bridge.
Though he is obviously more fondly remembered as a founding father of the United States of America, Thomas Jefferson was also a noted architect, employing neo-palladian ideals in designing the campus of the University of Virginia and in his homestead, Monticello. Jefferson can be found today on the front of the rarely-used 2 dollar bill.
