Abstract: Using the classification of the finite simple groups we show in this article that a faithful complex character $ \chi $ of a finite group $ G$ with a nonnormal T.I. Sylow $ p$-subgroup $ P$ has degree $ \chi (1){\text{ > }}\sqrt {\left\vert P \right\vert} - 1$. This result verifies a conjecture of H. S. Leonard [10].
