A few of Amsterdam's notable residents throughout its history include painters Rembrandt and Vincent van Gogh, seventeenth-century philosopher Baruch Spinoza, and the Holocaust victim and diarist Anne Frank. History Prehistory Due to its geographical location in what used to be wet peatland, the founding of Amsterdam is later than other urban centers in the Low Countries. However, around the area of what later became Amsterdam, farmers settled as early as three millennia ago. They lived along the prehistoric IJ river and upstream of its tributary Amstel. The prehistoric IJ was a shallow and quiet stream in peatland behind beach ridges. This secluded area was able to grow into an important local settlement center, especially in the late Bronze Age, the Iron Age and the Roman Age. Neolithic and Roman artefacts have also been found in the prehistoric Amstel bedding under Amsterdam's Damrak and Rokin, such as shards of Bell Beaker culture pottery (2200-2000 BC) and a granite grinding stone (2700-2750 BC),
