Johann Ludwig Bleuler, sometimes called Louis (12 February 1792 – 28 March 1850) was a Swiss painter, landscape artist and publisher.
His father, Johann Heinrich, was a landscape painter and member of the Schweizer Kleinmeister [sv] (lesser masters).
Beginning in 1827, he worked on a sequence of prints featuring landscapes and vedute along the Rhein; a project that would occupy him until his death.
His major work, Voyage pittoresque aux bords du Rhin et de la Suisse was published in 1845.
Many well known, or soon to be well known, artists were employed by his shop, including Egidius Federle, Konrad Corradi and Emanuel Labhardt.
