LEWISTON – There may be snow everywhere, but college graduations aren’t far off.

Two of four speakers at Bates College graduation will be the creator of the Segway, Dean Kamen, and children’s author Eric Carle.

Two other speakers at the May 27 ceremony will be singer-songwriter and Bates alumni Corey Harris, and actor-author Anna Deavere Smith.

All four speakers will receive honorary degrees, according to a press release from Bates College.

Inventor-entrepreneur Dean Kamen’s inventions include the two-wheeled personal transporter Segway, and health care innovations that have transformed daily living for many, such as the first wearable insulin pump for diabetics.

His other inventions are the HomeChoice portable dialysis machine, and the Independence iBot, a “super-wheelchair” whose sensors, microprocessors and gyroscopes allow people with mobility impairments to negotiate stairs and broken terrain.

One of his proudest creations is FIRST (For Inspiration and Recognition of Science and Technology), an organization to encourage students to use and enjoy science and technology. This year FIRST student competitions will involve more than 92,000 9- to 14-year-olds in 45 countries participating in FIRST’s LEGO League competitions.

Kamen’s most recent projects include systems to purify water and generate electricity in poor regions. He is president of DEKA Research and Development Corp. of Manchester, N.H.

Eric Carle made his fame with his illustrated picture books for children. His best-known work, “The Very Hungry Caterpillar,” has been translated into more than 30 languages and sold more than 25 million copies.

Since publishing “Caterpillar” in 1969, Carle has illustrated more than 70 books, including many best sellers, most of which he also wrote.

In 2002, Carle and his wife, Barbara, helped found the Eric Carle Museum of Picture Book Art in Amherst, Mass.

Acclaimed for his blues-based exploration of African diaspora music, singer-songwriter Corey Harris, a 1991 Bates graduate, began his musical journey with 1995’s “Between Midnight and Day,” a collection of traditional Delta blues songs. He has since made other CDs.

An anthropology major at Bates, Harris won a postgraduate Watson Fellowship to study pidgin English in Cameroon, then taught English and French in Napoleonville, La., traveling to New Orleans to perform on weekends. Music soon became his singular pursuit.

Hailed by Newsweek as “the most exciting individual in American theater,” playwright, actor, performance artist Anna Deavere Smith uses her theater style to explore race, community and character in America.

Smith is perhaps best known as the author and performer of two one-woman plays about racial tensions in American cities: “Fires in the Mirror: Crown Heights, Brooklyn and Other Identities,” a Pulitzer Prize finalist; and “Twilight: Los Angeles 1992,” which earned two Tony nominations.

The graduation will begin at 10 a.m. on the quad in front of Coram Library. In case of rain, the ceremony will be held in Merrill Gymnasium.
