Ludwig Blum was a Moravian-born Israeli painter who immigrated to Israel in 1923 as part of the Third Aliyah. He became widely known as "the painter of Jerusalem" for his lifelong dedication to depicting the city's landscapes and landmarks.

An academically trained artist, Blum worked in a realistic European style, producing detailed and atmospheric paintings. He focused primarily on the landscapes of Israel, especially Jerusalem and the Judean Desert, capturing their unique architecture, history, and natural beauty. His remarkable ability to portray the warm desert light, particularly at sunrise and sunset, gave his paintings a distinctive sense of depth and serenity.

Blum's works serve as both artistic masterpieces and historical records, documenting the changing landscapes of Israel during the first half of the 20th century. Today, his paintings are highly regarded by collectors and are represented in major museum and private collections.
