Measurements of the change in brightness of eclipsing binary star systems allow us to determine fundamental physical properties of the component stars that are necessary for modeling stellar evolution. Eclipsing binary systems that contain a delta Scuti component are especially interesting, because they provide critical information about these pulsating stars. Photometric observations of the Algol-type eclipsing binary system BO Her have led to the discovery that the primary component is a delta Scuti variable. Multifilter photometry of BO Her was carried out over ten nights during June and July, 2007, at the Truman Observatory using an 8-inch telescope and SBIG ST-7XME and ST-402ME CCD cameras. The primary component of the BO Her system pulsates in a single mode with a period of 1.7871 hours and with amplitudes of approximately 0.12 in the blue band, 0.08 in the visual band, and 0.05 in the infrared band.
