'Ellsworth Paine Killip (1890-1968), a botanist from the National Herbarium of the Smithsonian Institution who by chance was associated with the collection gathered by one of the great biological expeditions of modern times, the Royal Botanical Expedition led by Jose Mutis of Spain to the area known then as Nuevo Granada, an area that today would include large parts of northern South America and southern Central America. This monumental effort began in 1783 with the blessing of the Spanish Court and included botanical, biological and mineralogical surveys. Continuing for some thirty years, the expedition made a vast collection of specimens and descriptions, including some 6000 illustrations of 2700 plant species, possibly the greatest collection of botanical illustrations ever made. After the deaths of Mutis and his successor, Francisco Caldas, the King of Spain summarily ordered the collection shipped to the Royal Botanical Gardens of Madrid, where it languished essentially forgotten and unused until 1929. It was then that E.P. Killip began the enormous job of organizing it, a job whose fruition was not to be until the late 1953 with the publication of the first volume of illustrations. Thus far 23 volumes have been produced representing perhaps one-fifth of the species that were described by Mutis and Caldas.'

  Dr. Lincoln Constance (1909-2001), described as "the patriarch of botany at Berkeley," commented:-

'One of the botanists I met in Washington was Ellsworth Killip, quite an interesting chap. He was quite a good botanist. He had collected in both North and South America when it was quite the thing to do. His principal problem was that he a bit of an alcoholic, but he was fun to see at meetings if you didn't see too much of him, shall we say.

So far as I could discover, at any party he went on, he got sadder and sadder as the evening went along: and when he came out to Berkeley, I think he had hosted Lipman often, Lipman wanted to do something in return.'

A bit sad, but gives something of the character of the man.
