Isidore Rosenstock, known as "The Painter of Flowers," was an artist who seamlessly blended natural beauty with elegance. Born in Strasbourg in 1880, Rosenstock began his artistic career in Paris, gaining widespread recognition for his exceptional skill in watercolor painting. His work covered a broad range of subjects, including flower bouquets, the gardens of Versailles, Venetian landscapes, and various nature themes. In his pieces, he consistently highlighted the interplay of light, using delicate tones and precise forms to create a sense of grace and refinement. From 1905 onward, he was a member of the French Artists' Association, participating in numerous exhibitions and showcasing his works in galleries around the world. His reputation soared in the early 20th century, particularly through his participation in exhibitions at the Georges Petit Gallery in Paris, with his works also being featured in prestigious publications such as L'Illustration.

Rosenstock spent the latter part of his life on the French Riviera, in Lavandou, where he produced many works depicting the town's beaches, streets, typical boats, and fishing harbors. In 1939, due to the outbreak of the Second World War and personal challenges, he left Paris but continued to live through his art in Lavandou. In this small town, Rosenstock preserved his legacy by exhibiting his works in local galleries, maintaining his presence in the art world.

Rosenstock's works earned widespread acclaim both in France and internationally for their simple beauty and refined craftsmanship. In 2003, the exhibition Isidore Rosenstock, the Forgotten Watercolorist, held in Lavandou, helped to reignite interest in the artist's legacy and influence. In a tribute by the cultural director Myriam Ciano, Rosenstock's mastery of watercolor technique and his exceptional use of light were once again celebrated.
