Early life.
He was born at the Château d'Eu in France, the second son of Prince August of Saxe-Coburg and Gotha and Princess Clémentine of Orléans. His father was a first cousin of Victoria of the United Kingdom and her consort, Prince Albert of Saxe-Coburg and Gotha. Through his mother he was a grandson of Louis-Philippe I, the last reigning king of France.

The original plan was for August to marry Isabel and Gaston to Leopoldina, but the girls decided otherwise and the Emperor, having himself experienced the unhappinesses of an arranged dynastic marriage, agreed to their wishes.
Ludwig August and Leopoldina married in Rio de Janeiro on 15 December 1864, two months after the wedding of Isabel and Gaston. They had four sons:
His wife died young, aged 23, in 1871. He died on 14 September 1907 in Karlsbad, Germany, aged 62.
