Adam Eddington Intelligent, principled and a bit naive, 16-year-old Adam Eddington is a biology major who has been interning at
Woods Hole, Massachusetts in the summers, until "Old Doc" Didymus sends him to work with Calvin O'Keefe instead.
The Arm of the Starfish is Adam's first appearance in L'Engle's novels, and his only appearance in the O'Keefe series. He later appears in the Austin family novels
A Ring of Endless Light and
Troubling a Star.
Polyhymnia ("Poly") O'Keefe 12-year-old Poly is red-haired, and describes herself as having measurements of "twenty, twenty, twenty." Intelligent, inquisitive and loving, Poly speaks
English,
Spanish,
German,
Portuguese,
Russian, and Gaean.
The Arm of the Starfish is Poly's first appearance, as such, but Meg Murry O'Keefe was pregnant with her at the time of
A Swiftly Tilting Planet. Her unusual first name was bestowed on her by Canon Tallis, after which the O'Keefes did not allow him to name their other children. In later books, Poly begins to spell her name Polly to avoid awkward explanations about being named after
Polyhymnia, the Greek
muse of sacred music, and to keep people from pronouncing it with a long o.
Charles O'Keefe Charles O'Keefe is Poly's eldest younger brother, the closest to her in both age and companionship. Quiet, thoughtful and
empathic, Charles shows signs of having extraordinary
mental abilities, much like Charles Wallace Murry, the youngest maternal uncle for whom he is named.
Canon John "Tom" Tallis Canon Tallis is a bald clergyman with no eyebrows, said to have lost his hair due to withstanding torture in the
Korean War. Brusque and incisive, and not at all pious by L'Engle's definition, he defies the conventional image of a priest, and seems more than a little sinister to Adam at first. An
Episcopal Canon, he is surprisingly adept (but not perfect) at navigating the dangerous waters of international intrigue. Canon Tallis reappears in the Austin family novel
The Young Unicorns, where he is attached to the
Cathedral of St. John the Divine in
New York City, the same cathedral where Madeleine L'Engle was writer in residence for many years. He also appears in the second O'Keefe family novel,
Dragons in the Waters. Tallis is nicknamed "Tom" or "Father Tom" because of the historical composer
Thomas Tallis, who wrote the
Tallis Canon.
Dr. Calvin O'Keefe Calvin O'Keefe is a
marine biologist, husband of Meg, and the father of seven children, the eldest of whom is Poly. Calvin first appeared in
A Wrinkle in Time, as a 14-year-old high school junior, a popular and athletic but neglected adolescent from a family with eleven children. In this novel, his first name, Calvin, is never mentioned. As an adult, Calvin is a loving and attentive father. He was also an ambassador.
Margaret "Meg" Murry O'Keefe Meg O'Keefe is the former teenage Meg Murry, who rescued her long-lost father from the dark planet Camazotz in
A Wrinkle in Time. As of
The Arm of the Starfish, she is a scientist and mathematician (albeit without a doctorate) who assists her girlhood friend and husband Calvin with his work, while also helping to raise her large family. In contrast to her awkward adolescence, she is described as "a tall, strikingly beautiful woman" as an adult. ==Nomenclature==
