Lindt was a photographer, born at Frankfurt on Main, Germany, son of Peter Joseph Lindt, excise officer, and his wife Justine, née Rambach. At 17 he ran away to sea and joined a Dutch sailing ship. He deserted at Brisbane; by 1863 he was at Grafton as a piano-tuner and then worked in a photographic studio. He visited Germany in 1867 and on his return bought the business. Using the wet-plate process he photographed the Clarence River district and its Aboriginals, producing albums in 1875 and 1876.
