Herman the Bull (16 December 1990 – 2 April 2004) was the first genetically modified or transgenic bovine in the world.[1][2] The announcement of Herman's creation caused an ethical storm.[3]

Life[edit]

At the early embryo stage, Herman was genetically engineered in a laboratory by Gen Pharm International of Mountain View, California. Scientists microinjected cells with the human gene coding for lactoferrin. The Dutch Parliament changed law in December 1992 to allow Herman to reproduce. Eight calves were born in 1994 following a breeding program established at Gen Pharm's European laboratory Pharming Group N.V in Leiden, the Netherlands. All calves inherited the lactoferrin production gene.[4] With subsequent sirings, Herman fathered a total of 55 calves.[3]

Dutch law demanded he be slaughtered at the conclusion of his role in the experiment. The Dutch Agriculture Minister at the time, Jozias van Aartsen, agreed, however, to a reprieve, provided Herman did not have more offspring, after public and scientists rallied to his defence.[3]

Together with cloned cows named Holly and Belle, he lived out his retirement at Naturalis, the National Museum of Natural History in Leiden.[3] Herman the Bull was one of the oldest bulls ever in the Netherlands.[1]

Death[edit]

On 2 April 2004, Herman was euthanised by vets from the University of Utrecht because he suffered badly from osteoarthritis.[1][3]

Museum specimen[edit]

Herman the Bull's hide has been preserved and mounted by taxidermists; since 15 February 2008 Herman is permanently on display in Naturalis. According to Naturalis, the symbolic value of having Herman the Bull is that he represents the start of a new era in the way man deals with nature, an icon of scientific progress, and the subsequent public discussion of these issues.[1]
