Troost was born in Den Bosch, Netherlands, to Anna Cornelia (Van Heeck) and Everardus Josephus Troost, and the older brother of Benoist Troost.[2] He received the degree of Doctor of Medicine from the University of Leyden, and of Master in Pharmacy, in 1801, from the University of Amsterdam. After a brief practice at Amsterdam and the Hague, he was enlisted in the army as a private soldier, and then as an officer of the first class in the medical department. During these periods of service, he was wounded in the thigh and in the head.[1]
In 1807, Troost went to Paris under the patronage of Louis Napoleon, King of Holland. There he studied at the School of Mines with renowned mineralogist René Just Haüy. While in Paris, he translated into the Dutch language one of the earlier works of Alexander von Humboldt, The Aspects of Nature. This service brought him the cordial thanks of the author, with whom he maintained a friendly correspondence to the last.[1]
In 1810, he settled in Philadelphia, Pennsylvania. While there, he lectured on chemistry and mineralogy and made a geological survey of the area surrounding the city. Doctor Troost served five years as president of the Philadelphia Academy of Sciences.[3] In 1816, Troost was elected as a member of the American Philosophical Society.[4]

In 1825, he joined the New Harmony experiment, in New Harmony, Indiana, with Thomas Say. In 1827, he moved to Nashville, Tennessee, where he became a professor of mineralogy and chemistry at the University of Nashville. From 1831 until 1850, he served as the State Geologist of Tennessee. While there he sent animal specimens to John Edwards Holbrook. His most enduring contribution to science was his method of doing geological surveys, which was carried on by David Dale Owen, son of Robert Owen, who went on to do several surveys of the American northwest.[1]
In 1866, Dr. Benjamin F. Shumard named a genus of fossil blastoids Troosticrinus in his honor.[9]
In 1909, Elvira Wood edited and published Troost's unpublished monograph on the crinoidsofTennessee (1850).[10] This brought Troost's previously unknown work back into geological and paleontological discourse.
