Task: Question Answering
Input (English): Passage: Genetic engineers Clive Nicoli and Elsa Kast hope to achieve fame by splicing animal DNA to create hybrids for medical use at the company N.E.R.D. (Nucleic Exchange Research and Development). Their work previously yielded Fred, a dog-sized vermiform creature intended as a mate for their female specimen, Ginger. After successfully mating them, Clive and Elsa plan to create a human-animal hybrid that could revolutionize science. Their employers Joan Chorot of N.E.R.D. and William Barlow forbid them from doing this. Instead, they are to find and extract proteins used for commercial drug production from Fred and Ginger. Clive and Elsa, however, disobey their superiors and pursue their own agenda in secret, developing a viable prepubescent female creature.
Although they had planned to terminate the hybrid before it reached full term, Elsa persuades Clive to let it live. They discover that she is aging at a vastly accelerated rate. Elsa discovers that the creature is undergoing mental development such as that of a young human child. Elsa names the creature "Dren" after the creature spells out NERD, having seen the letters on Elsa's shirt.
After moving Dren to a new location for fear of discovery, they find she has a dangerously high fever. In an attempt to save her they place her in a large industrial sink filled with cold water. Later on Clive fully submerges Dren in the sink, and in doing so discovers that Dren is amphibious, but remains ambiguous in whether he tried to save Dren or kill her.
While studying Dren, Elsa and Clive neglect their work with Fred and Ginger. At a highly publicized presentation of their work, Fred and Ginger savagely fight to the death. It is subsequently discovered that Ginger had spontaneously changed to a male, but Elsa and Clive failed to notice because they were focused on Dren. 
Question: What are the first names of the people whose employers forbid them from creating a human-animal hybrid?
Output (English): Clive.
