Gotthard Daniel Fritzsche[p] (20 July 1797[b] – 26 October 1863) was a Prussian-Australian pastor who becoming instrumental in furthering that religion in South Australia. He was born in Liebenwerda, in the Electorate of Saxony, Germany, and migrated to Australia in 1841. From 1842–1863, he was pastor of the Evangelical Lutheran Church. He died and was buried at Lobethal, South Australia.
Gotthard Fritzsche went to Breslau after his gymnasium training, to receive his university training. There he studied under Johann Gottfried Scheibel. As was customary, after his university education, he served as a private tutor. At his first examination for entering the ministry, he declared himself to be against the Prussian Union, and was banned from ministry in the State church. He joined the underground Old Lutheran church as a Flying Pastor, who travelled from place to place disguised as a travelling tradesman, performing secret worship services and rites to those opposed to the State church. After a time, he grew weary of the work, and he travelled to Hamburg.
Fritzsche arrived in Hamburg when a group of Prussian Old Lutherans were searching for financing and a pastor to join their group in emigrating to South Australia. In 1840, at the synodical gathering of the newly constituted Lutheran Church in Australia, a request had been sent to the Old Lutherans in Prussia to send a second pastor to the young German settlement. A requirement had been imposed on them by the Prussian government, that they must be accompanied by a pastor before being allowed to emigrate.
Fritzsche was not eager to emigrate. He had already declined an invitation by Johannes Grabau to emigrate to the United States. However, he did relent to the requests of the people who were waiting to emigrate to South Australia. Fritzsche travelled to England to meet with George Angas in an attempt to gain financing for the balance of the fares, a sum of over £2000. Angas was unable to provide any financing to the group. It was in early June that a letter was received from a "Mrs. Richardson in Newcastle UK", with a sum of £270. The remainder of the required finances (£1800) was donated by one of the other emigrants, Mrs Anna (Hannchen) Nehrlich. Fritzsche had become engaged to her daughter Johanna Dorothea (Dorchen, Dorette), while in Hamburg.
