In memoriam: David Richard Hunt (1938-2019)
The members of the Executive Board of the International Organization for Succulent Studies are sorry to announce the loss of our friend and colleague David R. Hunt. David will always be remembered for being a distinguished member of our community, for his leadership in the area of cactus systematics and for being a great promoter of succulent plant studies, among many other things. David’s professional life cannot be separated from IOS. For decades, he used to voluntarily devote a considerable part of his time to stimulate the activities of IOS, always with the idea of fulfilling the central purpose of our organization: promoting the study and conservation of succulent plants of the world.
We express our sincere sympathy to his wife, Margaret Phillips, and to his friends and colleagues for the loss of this extraordinary man.
David D. Hunt
