“Sandgrube,” built in Basel, Switzerland, in 1746 as the home of Achilles Leissler (1723-1784), became this month the new location of the European Global Studies Institute in Basel. Achilles Leisler was a grandson of Jacob Leisler’s brother Franz Leisler. The Jacob Leisler Institute and the Europainstitut of Basel University are now collaborating in recovering the global connections of the Leisler family.
