Korats first appeared in Britain under the name "Blue Siamese" in 1889 and 1896, but these solid blue cats did not conform to the cat show judges' perception of a Siamese cat, and they disappeared by 1901. One early import, "Dwina", owned by Russian Blue breeder Mrs. Constance Carew-Cox and mentioned in Frances Simpson's "The Book of the Cat" (1903), reputedly produced a large number of "Siamese" kittens; the other, Mrs. B. Spearman's Blue Siamese male, "Nam Noi", was disqualified as a Siamese, but accepted in the Russian or Any Other Blue class in which he placed first (WR Hawkins, "Around the Pens", July 1896). Spearman tried unsuccessfully to import more of these "Blue Siamese".
