Thanks everyone so far for their thoughts.
I have another topic on this forum with the full photo of the man with the hat (photo on the left). It is the photo I received from a relative in England, but he did not know who they were. I will re-post it here to see if the dates make sense. I will tell you the story behind these photos.
John Brewster, My great great grandfather was a "porter" at the Royal Institution in London from around 1875 to 1910 when he retired. I recently got in touch with the RI and they were nice enough to send me any photos they had of the normal "day to day" workers at the Institution hoping I could recognize someone. After looking at the pictures this man seemed to look familiar to the photo I already had of a possible Brewster.
I have attached the photos in full for more detailed observations.
Thanks again, this site is really great
