Industrial biotechnology: Current status and future development for the sustainability of human society

摘要

Van Heel was also brought up with sailing on his father's yacht, a traditional Dutch vessel with leeboards, a so-called Vollenhovense Bol. The history and construction of these round- and flat-bottomed vessels took his interest, and he studied the building process of a traditional botter at the nearby shipyard of the fishing harbour of Huizen, Netherlands. In his Den Helder years, he published two papers (1960, 1962) on the history of the Vollenhovense Bol, the only Dutch traditional vessel of which we know how this type of vessel came into existence. In his student and Den Helder years, van Heel also enjoyed falconry as a hobby and as a means of studying animal training.
