Ohnimus's years of Capitol service closely mirrored that of his colleague, Joseph Beek, who served as Secretary of the upper house from 1913 to 1968.

He created job classifications, salary ranges, and personnel manuals, and laid the groundwork for the transition to a full-time legislature.

[4] He was routinely re-elected as Chief Clerk unanimously by Democratic and Republican members of the Assembly each year he sought office.

[8] Arthur Ohnimus was raised in the Western Addition neighborhood and attended Hearst Grammar School and Sacred Heart College.
