an interview, John Szarkowski describes his first encounter with the young Eggleston in 1969 as being "absolutely out of the blue". After reviewing Eggleston's work (which he recalled as a suitcase full of "drugstore" color prints) Szarkowski prevailed upon the Photography Committee of MoMA to buy one of Eggleston's photographs. In 1970, Eggleston's friend William Christenberry introduced him to Walter Hopps, director of Washington, D.C.'s Corcoran Gallery. Hopps later reported being "stunned" by Eggleston's work: "I had never seen anything like it." Eggleston taught at Harvard in 1973 and 1974, and it was during these years that he discovered dye-transfer printing; he was examining the price list of a photographic lab in Chicago when he read about the process. As Eggleston later recalled: "It advertised 'from the cheapest to the ultimate print.' The ultimate print was a dye transfer. I went straight up there to look and everything I saw was commercial work like pictures of cigarette packs or perfume bottles but the color saturation and the quality of the ink were overwhelming. I couldn't wait to see what a plain Eggleston picture would look like with the same process. Every photograph I subsequently printed with the process seemed fantastic and each one seemed better than the previous one." The dye-transfer process resulted in some of Eggleston's most striking and famous work, such as his 1973 photograph entitled The Red Ceiling, of which Eggleston said, "The Red Ceiling is so powerful, that in fact, I've never seen it reproduced on the page to my satisfaction. When you look at the dye it is like red blood that's wet on the wall... A little red is usually enough, but to work with an entire red surface was a challenge." At Harvard, Eggleston prepared his first portfolio, entitled 14 Pictures (1974). Eggleston's work was exhibited at MoMA in 1976. Although this was over three decades after MoMa had mounted a solo exhibition of color photographs by Eliot Porter, and a decade after MoMA had exhibited color photographs by Ernst Haas, the tale that the Eggleston exhibition was MoMA's first exhibition of color photography is frequently repeated, and the 1976 show is regarded as a watershed moment in the history of photography, by marking "the acceptance of colour photography by the highest validating institution" (in the words of Mark Holborn). Around the time of his 1976 MoMA exhibition, Eggleston was introduced to Viva,
