Hawley Olmstead became headmaster in 1839 and ended the line of short-termed schoolmasters as he held the position for ten years. Although Olmstead thought much like Hopkins' early masters, namely that the school existed to prepare boys for college, he also modernized the curriculum in several ways. Most notably, English was finally added to the curriculum, and he began keeping accurate school rolls which solidified his final legacy, increasing the size of Hopkins' student body. By the time Olmstead resigned due to poor health on July 28, 1849, school attendance had risen to 63 students.
