High school professors in republican scientific associations. The case of the Spanish Society of Natural History

The relevant role played by a notable group of secondary school teachers in the functioning of the Spanish Society of Natural History during the Republican years is presented in order to demonstrate two objectives. On the one hand, to show how university and secondary school teachers worked side by side in various scientific institutions created by the Junta para Ampliacion de Estudios e Investigaciones Cientificas; and on the other hand, to show how it was a widespread practice among a large contingent of secondary school teachers in the Republican years to combine teaching with research.
