As the Public Domain Review notes, the first recorded instance of the selfie harkens back to what may have been the first photographic portrait. In 1839, a young Philadelphia chemist named Robert Cornelius stepped out of his family’s store and took a photograph of himself:

'He took the image by removing the lens cap and then running [into the] frame where he sat for a minute before covering up the lens again. On the back he wrote “The first light Picture ever taken. 1839.”'
