The twin method is usually credited to Francis Galton's 1875 article on twins. However, Galton did not propose the comparison between identical and fraternal twin resemblance which is the essence of the twin method. Although the twin method was “in the air” in the mid-1920s, the first descriptions of the method appeared in an article by Curtis Merriman and in a book by Hermann Siemens, both in 1924, 50 years after Galton's paper.

Galton could not in 1875 have invented the classical twin method based on this non-Mendelian theory of heredity because he did was to track the life-history changes of twins to see whether twins who were very similar at birth diverged in later life or whether twinsWho were very dissimilar at birth converged later, as a test of the relative importance of nature and nurture.
