GAYRAND, HIPPOLYTE. – Theologian and public figure, born in Lavit (Tarn-et-Garonne) in 1856, died in Bourg-la-Reine on 17 December 1911. A Dominican from 1877, he taught theology and contemporary philosophy at the College of his Order and at the Catholic Institute of Toulouse. Having obtained from the Pope the faculty to lay aside the Dominican habit, in 1893 he abandoned teaching to devote himself entirely to politics and social propaganda. He was in fact elected deputy for the Brest constituency, occupying the royalist seat left vacant by the death of Monsignor d'Hulst; subsequently he was re-elected several times. He fought strenuously against the separation of Church and State, often imposing himself on the anticlericals.
Among his many works, the following are notable: *Thomisme et religion*, I: *Réplique au r. p. de Régon* (Toulouse 1889); *Providence et libre arbitre selon s. Thomas d'Aquin* (ibid. 1892); *St Thomas et le prédéterminisme* (Paris 1895); *L'antimétisme de s. Thomas d'Aquin* (ibid. 1896); *Les démocrates chrétiens* (ibid. 1899); *La Foi devant la raison* (ibid. 1905). He collaborated assiduously with the *Revue du clergé français* and the *Revue de philosophie*.
