Karl Vernon MM (19 June 1880 – 11 July 1973), sometimes known by his nickname The Bean, was a British rower and coach who competed in the 1912 Summer Olympics.

[2] In the Autumn of 1907, having become frustrated by their inability to impress the Thames coaches, Vernon and Beresford formed a new four with Logan and Charlie Rought.

These four (with Vernon in the 2 seat) would stay together, on and off, for the next five years, winning the Stewards' Challenge Cup at Henley in 1909 and 1911.

[3] In the First World War, he served with the Royal Army Medical Corps and was awarded the Military Medal.

He was a talented draughtsman and sketcher; Vernon's works were frequently used as prizes in local regattas.
