Ulrich Schmidl
Ulrich Schmidl or Schmidel (c. 1510 - 1581) was a German conquistador and chronicler. Between 1534 and 1554 he took part in the Spanish conquest of the Río de la Plata region. Upon his return to Germany in 1554 he wrote a narrative of his adventures in the New World. His account is one of the earliest and most important sources of information about the history of the region during that time period. Historians regard his account as generally reliable.
