Baron Daniel Tilas (tiles) (born March 2, 1712 in Gammelbo ( Västmanland ), † October 27, 1772 in Stockholm ) was a Swedish genealogist , heraldist , imperial herald , governor , mining engineer , mineralogist and geologist .

Life

Tilas was married twice. His wives were Hedvig Reuterholm in 1741 and Anna Katarina Åkerhielm in 1743. He had a son, the poet and writer Baron Samuel Olof Tilas (born August 29, 1744, † September 12, 1772).

His varied scientific life began in 1723 with studies at Uppsala University , which he interrupted from 1726 to 1728 and finished in 1732. He later worked as a lecturer at this leading Scandinavian institution. In the same year of his graduation, he got an assistant position at the mining office. Tilas was a member of a commission that dealt with the definition of the border between Sweden and Norway in 1745. He extensively documented the geological observations obtained during the site inspections.

He has acquired extensive knowledge through many trips to the northern regions of Karelia , Norway , Russia and Sweden . During a major fire in Stockholm, Klara district, where he lived in 1751, all of his documents and manuscript maps, especially his travel records, were lost, so that only a few testimonies of Daniel Tila's work have survived.

One of his merits was the knowledge of the necessity of mining mapping in the ore deposits and their surroundings. This mapping was a new form of the rational and planned development of a mining area . His efforts at such mapping work later proved to be groundbreaking, but were viewed critically by contemporaries.

Much of his written work dealt with Swedish mineralogy and geology. In recognition of his services, the mineral tilasite is named after him. Tilas was the founder, member and president of the Royal Swedish Academy of Sciences in 1739 and from 1740–45 he was the mine director. From 1745 Tilas was assessor in the Bergskollegium, later Bergsrat (1755) and from 1762 he was given the office of governor.

His elevation to the nobility, baron in 1766, paved the way for him to the office of Reichsheraldikers , which he accompanied from 1767/68 until his death in 1772. Tilas succeeded Conrad Ludvig Transchiöld in this position , who died in 1765 and the office after him led Anders Schönberg to his death from 1773 until 1809.

Merits

Tilas was the commander of the North Star Order and a long-time member of parliament.
