The bright stellar content of fifteen binary star clusters in the LMC was estimated, using film copies of plates taken with the 1.2 U.K. Schmidt telescope to derive the spectral types of the stars in the region. It was found that all classified stars are brighter than V = 17.5 mag and are situated in the large areas around each pair and in a neighboring field. The binary clusters were of different ages, from 8 x 10 to the 6th to greater than 6 x 10 to the 8th yr, indicating that the formation of binary clusters occurred at different stages of the Galaxy's dynamical history. Seven of the pairs, the brightest and the most populous, are young clusters. For these, both members of each pair exhibit the same stellar content.
