--On Jan. 30, 1858, what became known as McMinnville College, came to life. Its seal has the letter "M" in the middle.
--On June 6, 1922, McMinnville College became Linfield College. There were at least two Linfield College seals. One shows an open book. The other, which debuted in 2010, featured an acorn. See two versions of the open book version. The first may be the first used when McMinnville College became Linfield College. The second appears to be a version with more graphic clarity than the first. See yet another version. The Linfield College seal appeared on a cardinal colored felt pennant sold by the Linfield College bookstore. Cardinal and purple are Linfield's school colors.
--On July 1, 2020, Linfield College became Linfield University. The university’s seal has the letter "L" on a shield in the middle. It features the Old Oak.
