Cornelis Troost

Cornelis Troost was born in Amsterdam on 8 October 1696, though a small number of later reference sources give 1697. He initially pursued a career on the stage, training and performing as an actor and set painter at Amsterdam's Schouwburg theatre, where he worked from 1719 to 1724. Around 1723 he left the theater to study painting as a pupil of the portraitist Arnold Boonen, a transition documented in period and modern biographical sources, though its exact duration is not recorded and no formal schooling or degree is documented for any part of his training.

Troost's reputation as a painter was established with his 1724 group portrait of the Amsterdam Inspectors of the Collegium Medicum, now in the Rijksmuseum, which showcased the same eye for gesture and social choreography he had developed on stage. He went on to become one of the most sought after portraitists and genre painters working in Amsterdam, producing conversation pieces, theater related scenes, and comic domestic subjects. His most celebrated late work is the NELRI series of 1740, five pastel and watercolor panels now held together at the Mauritshuis, often cited as the high point of his technique.

Troost died in Amsterdam on 7 March 1750 and was buried in the city's Nieuwe Kerk.

Reference sources are consistent in ranking Troost as the outstanding Dutch painter of the eighteenth century. Art UK describes him along similar lines as the outstanding Dutch artist of the eighteenth century, and the French reference work Larousse calls him the most deservedly famous Dutch painter of that century, crediting him as the only Dutch artist of his time to adapt the country's painting tradition, and its illustrious genre scene, to new fashions drawn from both French fete galante painting and the satirical manner of Hogarth. The Rijksmuseum frames him similarly, noting that his intimate family portraits and humorous scenes drawn from stage plays made him one of the most important Dutch painters of the century. Because Troost worked before the era of exhibition catalogues and press reviews, this critical standing rests almost entirely on later art historical assessment rather than on contemporary reviews.

Troost's market today is a museum market rather than an active auction market. No catalogue raisonne of his work has been established, and public sale data are thin. The highest documented price identified in current research is a Sotheby's New York sale of Drinkenburg (The Morning After) for USD 639,000 in January 2019, with a second Troost painting, A Corps de Garde with Dutch Officers at Night, selling for USD 459,000 at the same house that month; the exact calendar date of each sale is not published in the sources available, so these figures should be treated as the best documented data points rather than a confirmed all time record. Troost's paintings and pastels appear only occasionally at auction; most significant works reside permanently in institutional collections such as the Rijksmuseum and the Mauritshuis, which remains the strongest signal of his standing rather than any auction pattern.

Troost is a historical, museum grade name rather than a liquid auction artist, and buyers should expect infrequent, unevenly documented sales rather than a steady run of comparables. The absence of a confirmed catalogue raisonne means attribution and condition review should rely on established institutions and specialists in Dutch old master painting, and provenance research should be treated as essential given how scarce public transaction records are. Anyone evaluating a purported Troost should also expect to encounter works in pastel and watercolor as well as oil, reflecting the range of techniques, including the NELRI series, that built his reputation.
