Christian Frederick(h) Schwarz (also Schwartz) (1726–1798) was a German Lutheran missionary to India.
Born on 26 October 1726 at Sonnenburg, in the electorate of Brandenburg, Prussia. His father was George Schwartz and his mother Margaret Grundt. Having learned Tamil to assist in a translation of the Bible into that language, he was led to form the intention of becoming a missionary to India. He received ordination at Copenhagen on 8 August 1749, and, after spending some time in England to acquire the English language, embarked early in 1750 for India.
He arrived at Tiruchirapalli on 30 July via Tranquebar. Tranquebar was for some time his headquarters, but he paid frequent visits to Thanjavur and Tiruchirapalli, and in 1766 moved to Tiruchirapalli. Here he acted as chaplain to the garrison, who erected a church for his general use.
In 1769, he secured the friendship of the king Raja Tuljaji, who, although he never converted to Christianity, afforded him every countenance in his missionary labours. Shortly before his death he committed to Schwarz the education of his adopted son and successor Sarabhoji (Serfoji). Schwarz taught the prince, Prince Serfoji, and another slightly older pupil Vedanayagam using the gurukulam approach, where the teacher and the pupil live together.Raja Serfoji built a church to show his affection to Schwartz and it is still seen as a symbol of tolerance on the part of that great Mahratta ruler towards different religions.
In 1779, Schwarz undertook, at the request of the British authorities in Madras (present day Chennai), a private embassy to Hyder Ali, the ruler of Mysore. When Hyder invaded the Carnatic, Schwarz was allowed to pass through the enemy's camp without molestation. In 1784 he established an English school in Thanjavur and this school is now known as St.Peter's Higher Secondary School. After twelve years in Tiruchirapalli he moved to Thanjavur, where he spent the remainder of his life. He died on 13 February 1798 just before Serfoji II ascended the throne. He was laid to rest in St.Peter's Church in Maharnonbuchavadi,Thanjavur. In his tomb there is a tombstone with a short memoir and an elegy in English written by Serfoji II.
