Célestino Alfonso (1 May 1916, at Ituero de Azaba, Salamanca province, Spain – 21 February 1944, at Fort Mont-Valérien, France) was a Spanish republican, a volunteer in the French liberation army FTP-MOI, and a part of the resistance operation led by Missak Manouchian. He was, by profession, a carpenter.
His name will be inscribed in the Panthéon on the entrance to Manouchian's crypt, making him the first Spaniard honored by the Panthéon.[1]
