Charles Doyle Leffler 'Uncle Charlie' (August 12, 1868 - April 27, 1939) was a business leader and politician.

[citation needed] In 1904 Leffler was elected to the Miami board of public works, serving for two years.

[6] The City of Miami charter was amended in January 1921 to change the executive position to a commission-city manager system.

A petition and lawsuit were filed with the local court to keep the serving city commissioners including Leffler, J.E.

The courts eventually sided with the incumbents, allowing them to continue their hold on Miami government into the late 1930's.
