## About Jan van Couver

Jan van Couver is a documented alternate name used by Hermanus Koekkoek the Younger (1836–1909), a Dutch painter and art dealer. Authority records connect the name directly with Koekkoek, while Dutch-language biographical material also records Louis van Straaten as another pseudonym. Koekkoek worked in marine and landscape painting and is especially associated with seascapes. This alias matters for collectors because catalogue entries and auction records may appear under different names even when they refer to the same artist identity. Works encountered as Jan van Couver should therefore be researched alongside records for Hermanus Koekkoek the Younger and the Dutch form Hermanus Koekkoek de Jonge. The available authority and biographical sources establish the identity relationship and broad artistic fields, but they do not support a more specific movement label or detailed working chronology. Appraisily accordingly treats the alias connection as the central entity fact rather than assigning an unsupported school.

## Common works and media

Collectors may encounter paintings described as marine views, seascapes, or landscapes. The source pack identifies the artist as a painter but does not document a distinct practice in prints, sculpture, ceramics, or editioned works. Relevant records should be searched under Jan van Couver as well as Hermanus Koekkoek the Younger, Hermanus Koekkoek de Jonge, and Louis van Straaten.

## Market and appraisal context

Appraisal research for a work catalogued as Jan van Couver should begin by reconciling the name with Hermanus Koekkoek the Younger and his other documented aliases. Marine subject matter, seascapes, and landscapes provide useful classification context, but identity and subject alone do not authenticate an individual object. When public auction records are available, the most relevant comparisons are records matched to the same artist identity and a similar work type. Sale date and realized price can then provide historical market context. The collected sources do not establish a price trend or document recurring condition, provenance, dimension, or edition patterns, so those object-specific factors require separate evidence before a value conclusion is formed.

## Appraisily data basis

Appraisily artist pages combine researched artist identity and alias relationships with auction records, auction-house context, sale dates, realized prices, and comparable lots when those records are available.
