John B. Trevor (1878–1956) was an enthusiastic amateur photographer and a New York lawyer.

Trevor photographed his family and friends (often illuminated by flash powder), flowers, landscapes, and objects from his art collection, including Oriental rugs and Chinese vases…

The Autochrome process in a nutshell: Autochromes were invented by Auguste and Louis Lumière. Autochrome plates were first patented in 1903, presented to the Academy of Science in 1904, and mass produced in Lyons, beginning in 1907. Each Autochrome is a unique color positive produced with millions of microscopic potato starch grains dyed orange-red, green, and violet-blue adhered to a varnished glass plate and coated with a photo-sensitive emulsion. The plates were relatively easy to use and the average exposure time was one second. The pointillistic potato particles are pitch-perfect and appealingly pleasant as pixels…

Addendum:
I identified two of these images incorrectly. The photographer’s great-grandson, Bronson Trevor III, corrected my mistakes. And called our attention to two more online exhibitions of images made by John B. Trevor:
one on Flickr
and another on Picasa…
Thanks.
