          Abstract: | 
           
              The main purpose of this paper is to use a Grüss type inequality for Riemann-Stieltjes integrals to obtain a sharp integral inequality of Ostrowski-Grüss type for functions whose first derivatives are functions of Lipschitizian type and precisely characterize the functions for which equality holds.
