Early Life & Education
We do not have too many details about John Stewart's grade school and high school years. He was born in in Tarentum, PA, in 1898, to John Thomas Stanier and Emma Fiddler. John was the youngest of three siblings. His father was an immigrant from England (or possibly Scotland) and his mother was born in Pennsylvania but his maternal grandparents emigrated from England. Tarentum is on the Allegheny River about 22 miles upstream of Pittsburgh. In the 1910 census (when John Stewart was 11 years old), the family is located in Tarentum in a rented home at 200 Lock St. There were 5 people in th household -- the parents John Thomas and Emma, and their 3 children. During the years of World War I (1917 and 1918 for the United States) John was of prime age for military service, and he did serve. See military service section. Census records from 1920 show that at age 21, the family was still in Tarentum. The home was owned and the address was 554 E. Eighth Ave. John Thomas was working as the superintendent of a steel mill (listed as a steel bar mill on the census) in 1920. There were a total of 5 persons in the house -- John Thomas and Emma, John Thomas and his older sister Anne, and a servant (Rose Witucki). Rose immigrated from Germany in 1902 and listed Polish as her first language on the census. John Stewart attended Lehigh University where he graduated in 1923. He was a member of the Sigma Nu fraternity (source, 1919 school yearbook as accessed on ancestry.com) and he was a member of the football team (source, school yearbook as accessed on ancestry.com).
John Stewart married Elizabeth Brydon Woolcott in 1926. He was 27 or 28 years of age and she was 23. The location of the wedding has not yet been determined. It could have been the bride's birthplace (Raleigh, NC), the town where the bride was brought up and where her parents probably lived in 1926 (Warren, PA) or elsewhere. John and Elizabeth had 3 children and 13 grandchildren. John Stewart Stanier was known to his grandchildren as 'Poppy.'
John Stewart Stanier was in the steel business. The 1930 census (age 31) lists him as a metallurgist in Newton Falls, OH. By age 41 (1940 census), he lists his occupation as steel mill superintendent in Youngstown, OH. Specifically, John Stewart went on to become superintendent of the Youngstown Sheet and Tube Company's Campbell Plant in Campbell, Ohio. The plant was visited by Eleanor Roosevelt in November, 1939. John Stewart is included in a picture  with the then first lady. John Stewart enjoyed Lake Chautauqua, New York. There are family stories told of guards stationed around the house to provide security during management-labor disputes.
The 1930 U.S. Census lists John S. Stanier as a veteran of World War I. Additional documentation of his military service has not been located yet.
Places of Residence

John Stewart Stanier's occupation is listed as metallurgist. It is interesting to note that a Howard Wolcott family (possibly a relative of John's wife Elizabeth) lived next door. Virtually everyone on the census form lists "steel mill" as employer.
