Construction began in 1921 on McPherson Chemical Laboratory, approved after the Department of Chemistry had outgrown Derby Hall. The original structure, designed by then-University Architect Joseph Bradford, was open for classes in autumn 1922.

A number of additions were added over the years and now surround the original structure. In 1999 the building was gutted and underwent extensive renovations to better serve the campus community.

On May 12, 1952, the Board of Trustees officially named the building to honor William McPherson, who taught chemistry for many years, organized the Graduate School and served as the University’s acting President, not once, but twice.

In 1883, McPherson enrolled at Ohio State in 1883 and would go on to receive three degrees from Ohio State (his bachelor’s in 1887, his master’s in 1890 and his doctorate in 1895). He taught at a Toledo high school after receiving his bachelor’s degree, and upon his return to Ohio State continued to teach chemistry. He went on to organize the Graduate School in 1911 and was named Dean in 1912, in which capacity he served until 1937.

His one break from teaching came during the World War I when he joined the Chemical Warfare Service, eventually being promoted to Lieutenant Colonel. After his return he was kept exceedingly busy: in 1924, for instance, he served as professor of chemistry, Dean of the Graduate School, and acting President of the University after William Oxley Thompson retired. He would serve as acting President again in the 1930s after the retirement of George Rightmire. On top of all of this, he wrote text books with Professor William E. Henderson; the sales of these books exceeded a million copies worldwide.

In 1938 McPherson retired, and he subsequently received from the University an honorary degree – doctorate of laws – and the title of president emeritus.

Dr. McPherson died on October 2, 1951, at the age of 87.
