Louis Daguerre introduced daguerreotypes in 1839.
The first photographs taken in the US were made in the spring of 1839 by two Harvard students: Edward Everett Hale and Samuel Longfellow. They repeated experiments per descriptions of Talbot's work published in American journals early in 1839. John Locke, of the Medical College of Ohio, publicly exhibited photogenic drawings (made without a camera by placing objects on sensitized paper, then exposing and processing) sometime early in about May 1839. Samuel Morse was the first to bring news of Daguerre's invention to the US via letters to his brothers, published in the New York Observer on May 18, 1839, and was one of the first to attempt the process when the instructions arrived in August, but the first documented Daguerreotype taken in the US was by a man named D.W. Seager, who had carried the French instruction manual from London to New York and had taken it directly to Morse. Seager's first Daguerreotype was a view of St. Paul's Church in New York City taken on September 16, 1839.

The First photo-1827 Joseph Nicephore Niépce produces the first successful picture over an eight hour exposure time. French inventor Joseph Nicephore Niepce uses a camera obscura to burn a permanent image of the countryside at his Le Gras, France estate onto chemical-coated paper. He names the technique heliography, meaning sun drawing. The black and white image exposure takes eight hours and fades significantly, but an image is still visible today.
