After great difficulty and much discouragement, Profes-sor Morse in 1835 demonstrated the practicability of his invention bycompleting and putting in operation in the New York university, a modelof his Recording Electric Telegraph—the whole apparatus, with theexception of a wooden clock which formed part of it, having been madeby himself. In 1837, he abandoned his profession, with great regret,hoping to make his invention a means of resuming it, under easier andmore agreeable circumstances. In the same year, he filed his caveat atthe patent-office in Washington ; and it is somewhat singular that, duringthis year (1837), Wheatstone, in England, and Steinheil, in Bavaria,both invented a magnetic telegraph, differing from the American and

Steinheils, on thecontrary, is a recording telegraph, but from its complicated and delicatemachinery, has been found impracticable for extended lines. At a con-vention held in 1851 by Austria, Prussia, Saxony, Wurtemberg, andBavaria, for the purpose of adopting a uniform system of telegraphingfor all Germany, by the advice of Steinheil, Professor Morses was theone selected. From the sultan of Turkey he received the first foreignacknowledgment of his invention in the bestowal of a nishan, or order —the order of glory: a diploma to that effect was transmitted to him withthe magnificent decoration of that order in diamonds. The second ac-knowledgment was from the king of Prussia, being a splendid gold snuff-box, containing in its lid the Prussian gold medal o
Louis Daguerre (1787–1851) was a French artist and inventor best known for his contribution to the development of photography. In 1839, he announced the invention of the daguerreotype, a photographic process that produced highly detailed and realistic images on a silver-plated copper plate. Daguerre's process involved exposing the plate to light for several minutes, then developing it with mercury vapour and fixing it with a salt solution. The resulting image was a unique, mirror-like reflection that captured every detail of the subject. The daguerreotype quickly became popular and was widely used for portraits and landscapes. Daguerre received numerous awards and honours for his invention, including a lifetime pension from the French government. Today, Daguerre is considered one of the pioneers of photography and his name is synonymous with the daguerreotype process. His legacy continues to inspire photographers and artists around the world.
