Hermann Anton Joseph "Tonny" Kessler (20 April 1889 – 15 February 1960) was a Dutch football player. Kessler - along with brother Dé and cousins Boeli and Dolf - played club football for amateur side HVV Den Haag. Kessler also won three caps for the Dutch national side between 1907 and 1913, scoring one goal. After playing alongside each other in a match against England in March 1913, the Kessler brothers became the first brothers to represent the Netherlands together in an international match.
