Sir – In the Photography Oxford Festival’s official newspaper, enclosed with The Oxford Times last week, Richard Ovenden refers to William Henry Fox Talbot variously as the ‘founder of photography’ and ‘father of photography’. Fox Talbot was neither.

He was a hugely important and influential figure in the history of photography, having invented the negative-positive process around 1835. However, that honour goes to Nicéphore Niépce, an unjustly neglected prolific inventor, who made photographs of real-world scenes at least as early as 1827.
