J. van Houten and I. van Houten-Groeneveld at Leiden on Palomar Schmidt plates taken by T. Gehrels. Rudolf Albert Kerkhoven (1879-1940) was a notable Dutch tea planter in Malabar, West Java, who, with his uncle Karel Albert Rudolf Bosscha, greatly contributed to the establishment of the Lembang Observatory. His legacy continues to support astronomical research in Indonesia and Holland.
