The magic of the architects James Pratt, Hal Box and Philip Henderson was not so much the thoughtful work they built, but what they suggested Dallas could be: a place of creative invention and human scale. That legacy will be explored in an evening program on Thursday, "Shaping Dallas Architecture," sponsored by DOCOMOMO North Texas and Preservation Dallas.

The firm was active from the 1950s through the 1980s, and its output included such beloved but lost spaces as the Apparel Mart (made famous by the film Logan's Run), the Olla Podrida arts mall and the much-compromised Quadrangle shopping center (pictured). Still-standing works include the free-form St. Stephen's Church in Mesquite, the modernist Texas Discovery Garden at Fair Park, and the campus of Brookhaven College.

But the firm's most dramatic project was not built: an 80-story tower for downtown Dallas that would have had an amusement park at its top.
