I enjoyed reading about the "Nature's Nation: American Art and Environment" exhibit on display at the Princeton University Art Museum in the Oct. 24, 2018, edition of PAW. However, I did want to note that the artist behind "Bridal Veil Falls, Yosemite" and whose work is the subject of Valerie Hegarty's "Fallen Bierstadt" is Albert Bierstadt, not Alfred as indicated in the article and accompanying caption. I realize this is a minor point that doesn't detract from the purpose of the article, but I also feel it is an important one. Thank you.
