Abstract
Complete uvby light curves are presented for the southern double-lined eclipsing binary TZ For. The light curves were obtained on 148 nights from 1976 through 1984 and contain 1175 points in each colour. TZ For consists of two evolved, but very well-separated, late-type stars (F7 III + G8 III) in a circular orbit (P = 75.7 d). It allows the first determination of highly accurate absolute dimensions for a normal giant star and provides a unique opportunity for testing current theories of stellar and tidal evolution.
