The invention of the daguerreotype in 1839 made portraiture much more commonplace, as many of those who were unable to afford the commission of a painted portrait could afford to sit for a photography session. This cheaper and quicker method also provided the middle class with a means for memorializing dead loved ones.Post-mortem photography was very common in the nineteenth century when "death occurred in the home and was quite an ordinary part of life. These photographs served as keepsakes to remember the deceased. This was especially common with infants and young children; Victorian era childhood mortality rates were extremely high, and a post-mortem photograph might have been the only image of the child the family ever had.(via ViralNova
