Joseph Rock first came to China in 1913, on a brief visit when he was almost thirty years old. He was on a world tour after taking extended leave from his position as a botanical researcher at the newly-established University of Hawaii. At a relatively young age, he had already achieved a great deal – in fact his accomplishments at 30 would have been regarded by many other men as sufficient reward for a lifetime’s work.

From humble beginnings as the son of a Viennese servant he had settled in the US and become a respected university academic and the author of several scientific publications that had garnered international acclaim. One of these, The Indigenous Trees of Hawaii is still a classic reference text on the subject.
