J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels. Willem Piso (1610-1678), doctor of medicine, together with Georg Marcgraf wrote the first book about the flora, fauna and the local customs of the Brazilians. Their book was and is an unique example of Brazilian society during the reign of the Dutch in Brazil.
