In the mid-twentieth century, American plant breeders, frustrated by their dependence on natural variation in creating new crops and flowers, eagerly sought technologies that could extend human control over nature. Their search led them to celebrate a series of strange tools: an x-ray beam directed at dormant seeds; a drop of chromosome-altering colchicine on a flower bud; a piece of radioactive cobalt in a field of growing crops. According to scientific and popular reports of the time, these mutation-inducing methods would generate variation on demand, in turn allowing breeders to genetically engineer crops and flowers to order. Creating a new crop or flower would soon be as straightforward as innovating any other modern industrial product. In Evolution Made to Order, Helen Anne Curry traces the history of America's pursuit of tools that could speed up evolution. Focusing on three key technologies x-rays, colchicine, and radioisotopes it is an immersive journey through the scientific and social worlds of mid-century genetics and plant breeding and a compelling exploration of American cultures of innovation. As Curry reveals, the creation of genetic technologies was deeply entangled with other areas of technological innovation from electromechanical to chemical to nuclear. Providing vital historical context for current worldwide ethical and policy debates over genetic engineering, Evolution Made to Order is an important study of biological research and innovation in America that will interest modern biotechnologists, biologists, and breeders, as well as historians of science and technology.
Plant breeders have long sought technologies to extend human control over nature. Early in the twentieth century, this led some to experiment with startlingly strange tools like x-ray machines, chromosome-altering chemicals, and radioactive elements. Contemporary reports celebrated these mutation-inducing methods as ways of generating variation in plants on demand. Speeding up evolution, they imagined, would allow breeders to genetically engineer crops and flowers to order. Creating a new food crop or garden flower would soon be as straightforward as innovating any other modern industrial product. In Evolution Made to Order, Helen Anne Curry traces the history of America’s pursuit of tools that could intervene in evolution. An immersive journey through the scientific and social worlds of midcentury genetics and plant breeding and a compelling exploration of American cultures of innovation, Evolution Made to Order provides vital historical context for current worldwide ethical and policy debates over genetic engineering.
Charting the political, social, and environmental history of efforts to conserve crop diversity. Many people worry that we're losing genetic diversity in the foods we eat. Over the past century, crop varieties standardized for industrial agriculture have increasingly dominated farm fields. Concerned about what this transition means for the future of food, scientists, farmers, and eaters have sought to protect fruits, grains, and vegetables they consider endangered. They have organized high-tech genebanks and heritage seed swaps. They have combed fields for ancient landraces and sought farmers growing Indigenous varieties. Behind this widespread concern for the loss of plant diversity lies another extinction narrative that concerns the survival of farmers themselves, a story that is often obscured by urgent calls to collect and preserve. Endangered Maize draws on the rich history of corn in Mexico and the United States to uncover this hidden narrative and show how it shaped the conservation strategies adopted by scientists, states, and citizens. In Endangered Maize, historian Helen Anne Curry investigates more than a hundred years of agriculture and conservation practices to understand the tasks that farmers and researchers have considered essential to maintaining crop diversity. Through the contours of efforts to preserve diversity in one of the world's most important crops, Curry reveals how those who sought to protect native, traditional, and heritage crops forged their methods around the expectation that social, political, and economic transformations would eliminate diverse communities and cultures. In this fascinating study of how cultural narratives shape science, Curry argues for new understandings of endangerment and alternative strategies to protect and preserve crop diversity.

Helen Stuart Campbell (born Helen Stuart; July 5, 1839 - July 22, 1918) was a social reformer and pioneer in the field of home economics. She wrote several important studies about women trapped in poverty, and the role that effective home economics could play in lifting women and families out of poverty.She was born in Lockport, New York to Jane E. (n e Campbell) and Homer H. Stuart. (She later changed her surname to favor her mother's maiden name.) She studied in Warren, Rhode Island and Bloomington, New Jersey. She worked as a professor of economics at the University of Wisconsin from 1893-96, and then as a professor of domestic science at Kansas State Agricultural College from 1896-97

Anne Bradstreet was the first American female writer as well as the first American female poet to have her works published.Anne Bradstreet (March 20, 1612 - September 16, 1672), n e Dudley, was the most prominent of early English poets of North America and first writer in England's North American colonies to be published. She is the first Puritan figure in American Literature and notable for her large corpus of poetry, as well as personal writings published posthumously. Born to a wealthy Puritan family in Northampton, England, Bradstreet was a well-read scholar especially affected by the works of Du Bartas. A mother of eight children and the wife of a public officer in the New England community, Bradstreet wrote poetry in addition to her other duties. Her early works read in the style of Du Bartas, but her later writings develop into her unique style of poetry which centers on her role as a mother, her struggles with the sufferings of life, and her Puritan faith...... Helen Stuart Campbell (born Helen Stuart; pen name, "Mrs. Helen Weeks"; July 5, 1839 - July 22, 1918) was a social reformer and pioneer in the field of home economics. She wrote several important studies about women trapped in poverty, and the role that effective home economics could play in lifting women and families out of poverty. Biography: She was born in Lockport, New York to Jane E. (n e Campbell) and Homer H. Stuart. (She later changed her surname to favor her mother's maiden name.) She studied in Warren, Rhode Island and Bloomington, New Jersey. She worked as a professor of economics at the University of Wisconsin from 1893-96, and then as a professor of domestic science at Kansas State Agricultural College from 1896-97. Publications: In the 1860s and 70s, she wrote stories and children's books under the name "Mrs. Helen Weeks". In later life, divorced from husband Dr. Grenville Weeks, Campbell - her new pen name - wrote novels and nonfiction works dealing with home economics and relationships between the individual, the home, the workplace, physical well-being, and childhood. She was active in many organizations that advocated female empowerment and associated with many intellectuals and original thinkers, including writer Charlotte Perkins Gilman. Much of her writing was engaging and vigorous. Her pieces exposed Gilded Age social inequities and public health failures. She was the author of a biography of 17th century colonial American poet, Anne Bradstreet.
