Zoel García de Galdeano y Yanguas (5 July 1846 – 28 March 1924) was a Spanish mathematician.

[1] His father was a military man, and was killed in war action, so his maternal grandfather, the historian José Yanguas y Miranda (1782-1863), took care of Zoel.

To continue his studies, in 1863, Zoel moved to Zaragoza, where he received the title of professor and expert surveyor.

In 1891, Zoel created El Progreso Matemático, the first strictly mathematical journal published in Spain.

He was also the first contemporary Spanish mathematician to regularly participate in international congresses of mathematics.
