In Joe Morgenstern’s review of the documentary “Eva Hesse” (The Wall Street Journal, May 13, 2016), he notes that in the film Grace Wapner, a fellow artist and friend, recalls Hesse saying that she didn’t care that her materials would degrade and that she threw a glass against a fireplace shattering it to illustrate what would happen to them. Hesse may not have cared that her work would degrade, but considering the amount of scholarship that has been dedicated to the condition and conservation of her works, a lot of other people do.
