There were a total of twelve governors during the Dutch colonial era.[1] The man sometimes said to be the thirteenth, Harmen Klenck van Odessen, was appointed by VOC Governor-General Joan Maetsuycker, only to arrive off the coast of Tayouan during the Siege of Fort Zeelandia. Klenck refused to go ashore to take up his post despite being urged to by Frederick Coyett, the incumbent governor, and finally left without ever setting foot on Formosa.[1]
