Quoting from wikipedia Sebright

 

Background
Sir John Saunders Sebright (1767–1846) was the 7th Sebright Baronet, and a Member of Parliament for Hertfordshire . In addition to breeding chickens, cattle and other animals, Sir John wrote several influential pamphlets on animal keeping and breeding: The Art of Improving the Breeds of Domestic Animals (1809), Observations upon Hawking (1826), and Observations upon the Instinct of Animals (1836).

Charles Darwin read Sir John’s 1809 pamphlet, and was impressed with a passage that elaborated on how “the weak and the unhealthy do not live to propagate their infirmities”. These writings, along with Darwin’s correspondence via their mutual friend William Yarrell, aided Darwin in the inception of Darwin’s theory of natural selection. Darwin’s seminal work On the Origin of Species, first published in 1859, cited Sir John’s experiments in pigeon breeding, and recalled “That most skilful breeder, Sir John Sebright, used to say, with respect to pigeons, that ‘he would produce any given feather in three years, but it would take him six years to obtain head and beak.'” Darwin also cited Sir John extensively regarding the Sebright bantam, as well as pigeon and dog breeding, in his 1868 work Variation of Plants and Animals Under Domestication, his 1871 The Descent of Man, and Selection in Relation to Sex, and his book on Natural Selection (which was not published in his lifetime).

Development
With the breed that carries his name, John Sebright intentionally set out to create a very small bantam chicken with laced plumage similar to the laced variety of Polish chickens. Although the exact makeup of the breed is uncertain, he is thought to have crossed British, Hamburgh, Nankin and Polish birds with a base of Rosecombs before achieving a laced chicken that would breed true. After the breed’s establishment circa 1810, Sebright founded The Sebright Bantam Club, which was the very first individual breed association for chickens. The breed has appeared in the American Poultry Association’s Standard of Perfection since the first edition in 1874. Today, the breed is one of the ten most popular bantam chickens, according to the American Bantam Association.
