Dr. Ruy d'Andrade was a Portuguese zoologist, paleontologist, anatomist, and historian. He was one of the - if not the - most highly respected experts on Iberian horses of his time. He was also a prominent and successful breeder of Lusitano/Andalusian horses. His line of horses is still one of the two most prominent and popular lines in the Lusitano breed. He was also instrumental in reconstructing the Portuguese breed Alter Real, a special line of horses within the Lusitano breed.
