Philip Green Gossler (1870-1945) was an electrical engineer and businessperson who spent his career working in public utilities, eventually becoming chair of the board of directors at Columbia Gas & Electric Company.

Gossler was born in Columbia, Pennsylvania, to Emily Morrison Washabaugh (1839-1908) and Colonel Philip Gossler (1815-1873). He received a Bachelor of Science degree in 1890 from Pennsylvania State College, followed by a degree in electrical engineering in 1892. He pursued a post-graduate course in electrical engineering at Columbia University in 1893.

Gossler worked for the Chester Foundry and Machine Company in Pennsylvania and the Edison General Electric Company in New Jersey from 1890 to 1891, when he became an assistant engineer at the United Electric Light and Power Company in New York, serving for four years. From 1895 to 1901, Gossler was superintendent and engineer of the Royal Electric Company in Montreal, Canada. The next three years, he was the general superintendent and engineer of the Montreal Light, Heat, and Power Company. He was vice president from 1904 to 1909 of J. G. White & Co. in New York, and various other concerns. From 1912 to 1922, he was chairman of the board of directors of Columbia Gas & Electric Company, which was the nucleus of the Columbia system, developed under Mr. Gossler's leadership. One of the largest public utility companies in the world, at the time of Gossler's death in 1945 Columbia Gas operated through thirty-four companies in New York, Pennsylvania, Ohio, West Virginia, Virginia, Kentucky, Maryland, and Indiana, serving more than 1,200 communities with an estimated population of 5 million with gas, electricity, water, heat, and transportation.

With the late George W. Crawford (1861-1935), president of the Ohio Fuel Corporation, Gossler in 1926 directed the merger of two of the leading natural gas systems in the country: the Ohio Corporation, with assets of more than $232 million, and Columbia, into the Columbia Gas and Electric Corporation. Gossler served as president of the new corporation from 1926 to 1936, when he became chairman of the board. He was a director of the Guaranty Trust Company of New York; a trustee of the Edison Electrical Institute; a former vice president of the Edison Pioneers and the New York Electrical Society; and a member of the American Institute of Electrical Engineers, American Gas Association, Association of Edison Illuminating Companies, Phi Kappa Sigma, and the Pennsylvania Society.

He married Mary Clafin (1873-1947) in 1895; the couple had three children: Mary Clafin Gossler (1897-1934), Katherine Gossler Clay (1900-1979), and Lieut. Col. Philip Green Gossler Jr. (1901-1978). Following a divorce in 1917, Gossler married Georgia Whiting Saffold (1890-1953) in 1938.
