The suggestion of a genetic relationship between Indo-European and Uralic is often credited to the Danish linguist Vilhelm Thomsen in 1869 (Pedersen 1931:336), though an even earlier version was proposed by Finnish linguist Daniel Europaeus in 1853 and 1863. Both were received with little enthusiasm. Since then, the predominant opinion in the linguistic community has remained that the evidence for such a relationship is insufficient. However, quite a few prominent linguists have always taken the contrary view (e.g. Henry Sweet, Holger Pedersen, Björn Collinder, Warren Cowgill, Jochem Schindler, Eugene Helimski, Frederik Kortlandt and Alwin Kloekhorst).
