Seiberling Company, his father's farm machinery manufacturing business, working there as secretary and treasurer.

[4] His father, John Seiberling, founder of that Akron, Ohio, company, invented one of the first reaping machines.

While working for the company, Seiberling invented a twine binder that tied grain bundles with a bow knot.

[5] Many businesses failed in the panics of the 1890s, including the street railway company owned by Seiberling's father.

The company would be named for Charles Goodyear, the discoverer of vulcanization, who had died penniless almost forty years before.

In June 1911, Seiberling announced that he was financing an attempt at a transatlantic airship flight, to be headed by Melvin Vaniman.

[10] During his lifetime, Seiberling used his fortune and influence to create fair housing, build a hospital, improve transportation both locally and nationally, preserve green space for the community's enjoyment and fund countless arts and culture programs and organizations.

"[11] Seiberling focused on projects that directly impacted the lives of his Goodyear employees and thereby ensured the success of Akron.

In addition, he was a founder of The Peoples Hospital, the Fairlawn Country Club, and the Metropolitan Park system in Akron.

Portions of the property were broken off during Seiberling's lifetime to create the Fairlawn Heights neighborhood and Sand Run Metro Park.

In 1887, he married Gertrude Ferguson Penfield, who was later to serve (1919–1921) as president of the National Federation of Music Clubs.

[13] The couple had seven children, three girls (Irene, Virginia, Grace Wenonah) and four boys (Fredrick, Willard, Penfield, and Franklin).
