(Lecture 2 of 2) In honor of The Impressionists: Master Paintings from the Art Institute of Chicago exhibition currently at the Kimbell in Fort Worth, Dr. Brettell will give two public lectures on private collectors of French avant-garde painting at 7:30 p.m., Oct. 7 and 14, in the Davidson Auditorium at the UT Dallas School of Management. Although the second lecture is titled Frederick Clay Bartlett: Post-Impressionism and Modern Art in the 1920’s, it is really about two important art patrons: Clay and Martin Ryerson. Bartlett’s private collection was given to The Art Institute of Chicago in 1926 and included major paintings by Cezanne, van Gogh, Seurat, Gauguin, Picasso, Hodler and Matisse. Ryerson’s gift in 1933, however, is said to be the most important in the museum’s history because of the range of important artists and historical periods represented, from Impressionists to Old Master paintings.
