Hippolyte Bayard (20 January 1801 – 14 May 1887) was a French photographer a pioneer in the history of photography. He invented his own process known as direct positive printing and presented the world's first public exhibition of photographs on 24 June 1839. He claimed to have invented photography earlier than Louis-Jacques Mandé Daguerre in France and William Henry Fox Talbot in England, the men traditionally credited with its invention.[1]


Early life and career

While working as a civil servant, Bayard experimented with photography. He developed his own method of producing photos called the Direct positive process.[2] It involved exposing silver chloride paper to light, which turned the paper completely black. It was then soaked in potassium iodide before being exposed in a camera. After the exposure, it was washed in a bath of hyposulfite of soda and dried.

The resulting image was a unique photograph that could not be reproduced. Due to the paper's poor light sensitivity, an exposure of approximately twelve minutes was required. Using this method of photography, still subject matter, such as buildings, were favoured. When used for photographing people, sitters were told to close their eyes so as to eliminate the eerie, "dead" quality produced due to blinking and moving one's eyes during such a long exposure.

In the summer of 1851, along with photographers Édouard Baldus, Henri Le Secq, Gustave Le Gray, and O. Mestral, Bayard travelled throughout France to photograph architectural monuments at the request of the Commission des Monuments Historiques.[3]


Self Portrait as a Drowned Man

Bayard was persuaded to postpone announcing his process to the French Academy of Sciences by François Arago, a friend of Louis Daguerre, who invented the rival daguerreotype process. Arago's conflict of interest cost Bayard the recognition as one of the principal inventors of photography. He eventually gave details of the process to the French Academy of Sciences on 24 February 1840 in return for money to buy better equipment.

As a reaction to the injustice he felt he had been subjected to, Bayard created the first staged photograph entitled, Self Portrait as a Drowned Man. In the image, he pretends to have committed suicide, sitting and leaning to the right. Bayard wrote on the back of his most notable photograph:

The corpse which you see here is that of M. Bayard, inventor of the process that has just been shown to you. As far as I know this indefatigable experimenter has been occupied for about three years with his discovery. The Government which has been only too generous to Monsieur Daguerre, has said it can do nothing for Monsieur Bayard, and the poor wretch has drowned himself. Oh the vagaries of human life....! ... He has been at the morgue for several days, and no-one has recognized or claimed him. Ladies and gentlemen, you'd better pass along for fear of offending your sense of smell, for as you can observe, the face and hands of the gentleman are beginning to decay.


Late career

Despite his initial hardships in photography, Bayard continued to be a productive member of the photographic society. He was a founding member of the French Society of Photography. Bayard was also one of the first photographers to be commissioned to document and preserve architecture and historical sites in France for the Missions Héliographiques in 1851 by the Historic Monument Commission. He used a paper photographic process similar to the one he developed to take pictures for the Commission. Additionally, he suggested combining two negatives to properly expose the sky and then the landscape or building, an idea known as combination printing which began being used in the 1850s.
