Which came first, photography or the telephone?

photography came first, by 50 years. Niépce made the oldest surviving photograph from nature.

Side by side

photography

Joseph Nicéphore Niépce's View from the Window at Le Gras, made around 1826 or 1827 on a pewter plate coated in bitumen, required an exposure of at least eight hours. Daguerre's process of 1839 cut that to minutes and made photography practical. Photography therefore predates the telephone by half a century and the fax machine by seventeen years.

the telephone

Bell's patent was granted on 7 March 1876 and he made the famous call to Watson three days later. Elisha Gray filed a caveat for a similar device on the same day in February that Bell filed his application, and the priority dispute has never entirely gone away. Antonio Meucci had demonstrated a working voice telegraph in New York in 1860 but could not afford to renew his caveat.
