Abstract content <br> &nbsp; (Max 300 words)

We present reduction and analysis on two eclipsing Algol type binary systems from data obtained by the Kepler Satellite. KIC star A with parameters more indicative of an evolved Algol system (q = 0.36; TPrimary = 7300K, TSecondary = 4900K) shows no pulsation of the primary component of any description, whilst KIC star B, a theoretically less evolved system (q = 0.36; TPrimary = 8600K, TSecondary = 5300K) shows strong pulsation frequencies down to 8 x 10-4 magnitude. We suggest possible reasons for the lack of pulsation in KIC A and address the shortfalls of our understanding of Algol systems.
