Several years ago I took an art history course which covered the period from slightly pre-Renaissance through the early twentieth century. The instructor very briefly discussed an artist who was active in the United States in the early twentieth century. He was most active around 1910, if I remember right. The similarities between him and Edward Hopper were so blatant that I incredulously asked the instructor “was Hopper ripping this guy off?” The instructor didn’t directly answer the question, but she said something like “I would be very surprised if Hopper were unaware of his work.” First of all, he heavily favored watercolors. Also, all of his works that the instructor showed us had a heavy bluish-green cast to them, just like most of Hopper’s interior scenes. They also invariably portrayed themes involving isolation and loneliness, and were mostly street scenes. The only work I remember clearly depicted an elevated train, with (I think) a lone elderly woman looking out one of the windows. I’ve scoured Mark Harden’s Artchive and every other online source I can think of trying to identify him, to no avail. Who could this have been?
