Arthur Ford Mackenzie (06-10-1861 - 23-06-1905) Jamaican composer

Arthur Ford Mackenzie

Arthur Mackenzie lost his eyesight in 1896 but continued to compose chess problems. His 282 problems were compiled by A.C. White in "Chess Lyrics" in 1905: it was the first volume of the White Christmas series, which can be downloaded and read from here.
More details about this Jamaican citizen can be found on arthurfordmackenzie.20fr.com. He wrote and published in 1897 in Kingston the book "Chess: Its Poetry and Its Prose", as recalled Edward Winter in his Chess Notes.

His most famous problem may be this one:

International Judge and twomover composer, Efim Rukhlis revolutionized the twomovers in the 1960s with his theme, that involves at least two transferred mates and on the same black defences two changed mates.
He composed more than 300 Ideal-Rukhlis twomovers, according to Milan Velimirović in his article "Ideal Ruchlis - A comprehensive overview" in Mat Plus Review, 9-10. Spring-Summer 2009.

Let's see an example from 1946:
