Ludwig I von Lichtenberg
Ludwig I von Lichtenberg (first attested 1206, died 1252) was an Alsatian nobleman. He was lord of Lichtenberg and Vogt of Neuweiler.
He was the father of Ludwig II and Heinrich II, who carried on the secular lordship, and of Conrad III and Friedrich I, who both became bishops of Strasbourg; his other sons also entered the church. The later Lichtenberg lords all descended from his line.
