The fascinating, little-known story of how two brilliant female physicists’ groundbreaking discoveries led to the creation of the atomic bomb.

In 1934, Irène Curie, working with her husband and fellow scientist, Frederic Joliot, made a discovery that would change the world: artificial radioactivity. This breakthrough allowed scientists to modify elements and create new ones by altering the structure of atoms. Curie shared a Nobel Prize with her husband for their work. But when she was nominated to the French Academy of Sciences, the academy denied her admission and voted to disqualify all women from membership. Four years later, Curie’s breakthrough led physicist Lise Meitner to a brilliant leap of understanding that unlocked the secret of nuclear fission. Meitner’s unique insight was critical to the revolution in science that led to nuclear energy and the race to build the atom bomb, yet her achievement was left unrecognized by the Nobel committee in favor of that of her male colleague.

The story of two women breaking ground in a male-dominated field, scientists still largely unknown despite their crucial contributions to cutting-edge research, in a nonfiction narrative that reads with the suspense of a thriller. Photographs and sidebars illuminate and clarify the science in the book.


"A thorough and engaging study of two female scientists worth their weight in radium."—Booklist, starred review

"In this thorough and clear dual biography, Conkling profiles two 20th-century scientists whose contributions facilitated the creation of the atomic bomb--to their horror. Though Lise Meitner (1878–1968) and Irène Curie (1897–1956) shared an idealistic and passionate devotion to physics, they were often rivals and never worked collaboratively...Both highly educated women struggled against chauvinist attitudes: Curie's efforts to join the French Academy of Science were repeatedly turned down, while Meitner never received a Nobel Prize despite 15 nominations. Conkling successfully redresses that lack of recognition here. A glossary, time line, and extensive "Who's Who" section provide additional context, along with explanatory sidebars and b&w photos."—Publishers Weekly

"Using a conversational tone, the author has written a book about historical figures involved in complex science that remains accessible for readers without prior knowledge of these topics. The inclusion of original photographs and images, additional brief explanations of scientific concepts, and a timeline of significant events connected to subjects covered is an unexpected bonus. Teens looking for material to complete a research paper will be glad to find this easy-to-read, fact-filled resource."—VOYA

"The contributions of two overlooked female scientists are made clear in this enlightening read...Luminous and fascinating, it recounts the lives and amazing findings of chemist (and daughter of Curie) Irène Joliot-Curie, codiscoverer of artificial radiation, and physicist Lise Meitner, codiscoverer of nuclear fission. Traversing the vicious landscapes of World War I and II and beyond, Conkling thoroughly explains the scientific explorations of each woman while describing their struggles being taken seriously as scientists even after Marie Curie had blazed a bright trail. Archival photos and primary source quotes enhance the story."—School Library Journal

"With a great sense of storytelling, author Winifred Conkling introduces two physicists whose major discoveries also brought about more equality and anti-war awareness in the sciences...Radioactive! addresses serious topics like the advent of chemical and atomic warfare and the Nazi rise to power, and leaves biography buffs wanting to know more in the best way."—BUST Magazine

Read Winifred's essay about writing the book

The page-turning, heart-wrenching true story of one young woman willing to risk her safety and even her life for a chance at freedom in the largest slave escape attempt in American history.

In 1848, Emily Edmonson, thirteen, along with five siblings and seventy other enslaved people, boarded the Pearl in the Potomac River in Washington, D.C., in a bid to reach freedom. Within a day, the schooner was captured, and the six Edmonsons were sent to New Orleans to be sold. Emily and Mary were saved from the even crueler conditions when the threat of yellow fever forced their return to Virginia. They were eventually ransomed with the help of their parents and abolitionists, including Harriet Beecher Stowe, who later used them as models for characters in Uncle Tom’s Cabin. Both girls went to Oberlin College, where Mary died of tuberculosis. Emily graduated and became a teacher at the first school in Washington, D.C., dedicated to the education of African American girls and young women–an idea so controversial that even Frederick Douglass advised against it. Emily also worked on behalf of abolition for the rest of her life.

Passenger on the Pearl illustrates a turbulent time in American history as seen through the daily lives of enslaved people; the often changing laws affecting them; the high cost of a failed attempt to reach liberty; the fate of all fourteen of the Edmonson children and their mother, Milly, whose goal to die a free woman shaped the lives of all her children; and the stories of the slave traders and abolitionists whose lives intersected with the Edmonsons’.


"This title is an in-depth historical narrative concerning several people involved in an attempted slave escape in 1848...Conkling narrates the tumultuous stories of Edmonson, her family, and the others involved, tracing their lives from their ill-fated jail escape to the slave auctions, the Deep South, and finally to freedom. Readers will discover how Edmonson came into contact with important figures in the antislavery movement, including Frederick Douglass, Rev. Henry Ward Beecher, and Harriet Beecher Stowe. Primary documents give an authentic voice to the text, including excerpts from Frederick Douglass's autobiography. Nineteenth-century plates, illustrations, photographic portraits, and posters enhance the text. Historical photographs of slaves and slave pens are particularly moving. Maps clearly outline the geography relevant to the narratives, and frequent text blocks separate contextual information from the primary narrative. This work covers information about slavery that is often not found in other volumes...Conkling's work is intricate and detailed, and...this is a strong and well-sourced resource."—School Library Journal

"Clearly written, well-documented, and chock full of maps, sidebars, and reproductions of photographs and engravings, the fascinating volume covers a lot of history in a short space. Conkling uses the tools of a novelist to immerse readers in Emily's experiences. A fine and harrowing true story behind an American classic."—Kirkus Reviews

""Passenger on the Pearl is a great resource for teaching young readers about the tragedy of slavery, as experienced by a girl their own age.&qout;—Historical Novels Review

Sylvia never expected to be at the center of a landmark legal battle. All she wanted was to enroll in school.

Aki never expected to be relocated to a Japanese internment camp in the Arizona desert. All she wanted was to stay on her family farm and finish the school year.

The two girls certainly never expected to know each other, until their lives intersected in Southern California during a time when their country changed forever.

Here is the remarkable story based on true events of Sylvia Mendez and Aki Munemitsu, two ordinary girls living in extraordinary times. When Sylvia and her brothers are not allowed to register at the same school Aki attended - instead, they are sent to a "Mexican school" - the stage is set for Sylvia's father to challenge in court the separation of races in California's schools. Ultimately, Mendez vs. Westminster School District led to the desegregation of California schools and helped build the case that would end school segregation nationally.


"Told in alternating chapters from the girls' points of view, this story about institutional racism will enlighten readers to events in recent history. From the court case of Mendez v. Westminster to the conditions at Poston, readers will be moved by this novel based on true events. Back matter include notes about the Mendez and Munemitsu families, essays on internment camps and the end of school segregation, and photos of Sylvia and Aki as children."—School Library Journal

"A well-documented, quietly powerful story."—Kirkus Reviews
