==Career==
Robert Gunderson began his work with the Genealogical Society of Utah in 1964.〔(【引用サイトリンク】title=Schoumatoff Interview (1977?) )〕 He started the Royalty Identification Unit in 1972 and served as Senior Royalty Research Specialist.〔 Among other projects, he and his assistants attempted to identify all the descendants of Edward IV of England.
In 1980, Gunderson first propounded the concept of ''Pedigree Collapse'' at the World Conference on Records in Salt Lake City, Utah. In his address, ''Connecting Your Pedigree Into Royal, Noble and Medieval Families'', he described how reproduction between two individuals who share a common ancestor causes the number of distinct ancestors in the family tree of their offspring to be smaller than it would otherwise be.〔(【引用サイトリンク】title=Roots Web Forum )〕
