About Graciano Ricalde Gamboa
- Mauro Graciano Ricalde Gamboa (November 21, 1873 – November 9, 1942) was a notable Mexican mathematician. Ricalde Gamboa was born in Hoctun, state of Yucatan, Mexico.
- Son of Don Ambrosio Ricalde Moguel and Isidra Gamboa and studied at Hocaba until 1885, the year he received a scholarship to the Normal School for teachers of the State in the city of Mérida.
- He graduated as a teacher at the age of 16 years, and because of his young age, was granted special permission by the State Congress. He studied accounting and for several years was a professor of commercial arithmetic books and accounts at the School of Commerce of the city Mérida.
- For the purpose of continuing his education, he studied civil engineering at the Institute for Literature of the state of Yucatan, under the wise leadership of Manuel Cepeda Sales.
- At that time, facing the danger of a collapse of one of the towers of the Cathedral of Yucatan, the authorities asked the teacher Sales Cepeda to assist in determining the weight of the church bell that had been ignored.
- The teacher passed the problem on to Ricalde Gamboa who did the calculations exactly.
- Since then he was appointed a professor of rational arithmetic at the Institute where he studied.
- For various reasons he could no longer continue his desire to study engineering, but soon after, in 1902, he was appointed professor and later director of his own engineering school, a position he continued until 1905 when he resigned to devote himself to the studies of mathematics and became a correspondent for various specialized institutions abroad. He assembled a large library of over 5000 titles and was a collaborator of the French academic journal L'Intermédiaire des Mathématiciens, published in Paris in the early twentieth century.
