Alfonso del Castillo Ochoa

Alfonso del Castillo Ochoa (1887 – 19 December 1962) was a Spanish footballer who is widely regarded as one of the most important figures in the amateur beginnings of Real Betis, being one of its first founders in 1907, and then serving the club as its first president from 1907 until 1909. His younger brother Juan was also president of Betis. He completed his studied in Seville, earning a degree in mining engineering. A board of directors was subsequently elected, with Alfonso being appointed as the club's first president, a position that he held for two years, until 1909, when he was replaced by his brother Juan.

Legacy On the occasion of the club's centenary, Betis called numerous of his relatives in Cartagena to inquire about photos and information for the "Centenary Book", which was published a couple of years later.
