 The "Éléments" became an influential series in 20th century mathematics, and Hermann benefitted in its role as publisher.Decades later, during the 1970s, Bourbaki and Hermann entered an extended legal battle over matters of copyright and royalty payment.The suit was resolved toward the end of the decade, with the result that Bourbaki retained copyright of its work and volumes of the "Éléments" would be printed by other publishers, going forward.
