Charles Roy Henderson

from Wikipedia, the free encyclopedia

Charles Roy Henderson (born April 1, 1911 at Coin , Iowa , USA; † March 14, 1989 in Urbana , Illinois , USA) was an American animal breeding scientist and biostatistician.

Live and act

He was the son of a farmer in the US state of Iowa and studied agriculture at Iowa State University in Ames (Iowa) with Jay Lush and Lanoy Nelson Hazel, among others . His specialty was initially animal nutrition , in which he received the two degrees B. Sc. and M. Sc. reached. This was followed by a job as an agricultural consultant and four years of military service in the US Army.

In 1948 he did his doctorate with Lay Lush and Oscar Kempthorne in the subject combination genetics / mathematical statistics for Ph.D. and became a private lecturer. From 1948-76 he was professor of animal breeding and head of the associated institute at Cornell University in Ithaka , NY, and developed his groundbreaking models for more reliable genetic valuation in animal breeding. In his retirement he was still a visiting professor at the Universities of Guelph (Canada) and Urbana-Champaign , Illinois (USA). In addition, he conducted many advanced training courses for young animal breeding scientists.

Building on the preliminary work of Sewall Wright and Jay Lush as well as Ronald Fisher and Frank Yates , Henderson developed new approaches for animal breeding sciences and the statistics required for them:

  • theoretical work on dividing the genetic variances into additive, dominant and epistatic components,
  • Suggestions for estimating the general and specific combination suitability of breeds in crossbreeding programs,
  • Method for estimating variance components in the case of unbalanced (not evenly distributed, i.e. also partially missing) data,
  • Proposals for estimation methods for mixed models and their systematic introduction to the breeding value estimation of domestic animals ( BLUP : Best Linear Unbiased Prediction - best linear undistorted prediction)

The BLUP process was tested in the US insemination organization "Eastern Artificial Breeders", later adopted worldwide and ensured the large increase in performance in dairy cattle breeds .
