Elihu later became the name of a "senior society" founded in 1903 at Yale.

The archives contain the history of other secret and senior societies.

The senior society died off in the 1960s.

According to the college, "approximately 25% of the senior class members are affiliated with a senior society."

The three remaining senior societies no longer operate as publicly but continue to serve the University in a variety of functions.

In 1923, an honorary senior society called Bisonhead was founded.

The solution led to the punishment of a secret undergraduate senior society and 16 of its members.

Only the senior societies survive from those early class societies, and new ones have been added in recent years.

About 10% of the senior class members are affiliated with a senior society today.

Members were then encouraged to move on to the senior society once old enough.
