Cornelis van Quaelberg
Cornelis van Quaelberg, also written as van Quaelbergen or van Quaalberg was the third commander of the Dutch Cape Colony from 1666 to 1668.
Van Quaelberg began his career in the service of the Dutch East India Company in Masulipatam, India, where he became Commander in 1652. He was transferred to the Cape in 1666. Two years later he fell out of favour and was fired in 1668 after lending help to a French fleet which he did not know was an enemy because news of the outbreak of war spread slowly. His good name was later restored and he was promoted to Governor of Banda in East India. Van Quaelberg died on 3 February 1687 in Republic of the Seven United Netherlands.
