In 1877, the Academy, located in the then newly-formed state of West Virginia, was renamed the Linsly Military Institute in honor of its founding benefactor.

[8] The school's first location was in downtown Wheeling, purchased with the sale of two farms that Noah Linsly had left to the Lancastrian Academy.

[11] Louis Bennett Jr. never attended Linsly but is memorialized by a statue, "The Aviator", outside of Banes Hall, one of 7 that his mother commissioned in his honor.

Bennett joined the Royal Flying Corps in World War I and defeated enough German aircraft to become an ace before being shot down over France.

The Lancastrian Academy system required older students to reinforce their education by mentoring their younger peers.

In 1979, Headmaster Reno Diorio transitioned Linsly to a traditional college preparatory school format.

[14] As a day and boarding school, Linsly is home to international students from many countries, including China, Finland, Canada, South Korea, Spain, Argentina, Costa Rica, Germany, Italy, Serbia, Brazil, and Japan.
