FAIRFIELD — The Pequot Library was closed Thursday, as employees honored the life of a favorite children’s librarian.

Susan Ei, 64, and known as Miss Susan to children and parents, died March 30 after a battle with cancer. Ei joined the library in March 2003, and was promoted to full-time children’s librarian in 2005.

“The loss of Miss Susan will be felt in our hearts for a long, long time,” said Stephanie J. Coakley, the library’s director. “Susan was deeply committed to everything Pequot Library, especially its young readers, and we will greatly miss her incredible spirit for life, selfless and generous character, stylish flair and unique talents and wisdom when it came to inspiring children to love reading and learning.”

Ei was the driving force behind many Pequot traditions, including the Easter egg roll, the annual potluck supper and campout, and bike parade on July 4, and the candy-making workshop.

Last year, according to a statement from the library, Ei welcomed 6,594 children to her programs, like the weekly storytimes for children.

Ei also started the Pequot’s “Read to Our Bunny” program, where parents and children can make an appointment to read to the real bunny that lives at the library. Children can “check out” the resident bunny for a stroll around the neighborhood, and many plant herbs in the garden on the library’s grounds to help feed the bunny.

Ei held a master’s degree in linguistics and a bachelor’s in art history. Before joining the library, she taught English as a second language.

“Ei had a special talent to inspire children to want to explore the natural world around them through engaging programs about science experiments, and even workshops about beekeeping. Most of all, she ignited a passion for reading in children of all ages with interactive Summer Reading programs and personalized book recommendations,” read the library’s statement.
