It was not easy being a woman of ambition in early 20th-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy", she was the first to describe what stars are made of.

Antoine Lavoisier reinvented chemistry, overthrowing the long-established principles of alchemy and inventing an entirely new terminology, one still in use by chemists. Madison Smartt Bell’s enthralling narrative comes across like a race to the finish line, as the very circumstances that enabled Lavoisier to secure his reputation as the father of modern chemistry—a considerable fortune and social connections with the likes of Benjamin Franklin—also caused his glory to be cut short by the French Revolution.

Edwin Grosvenor writes of Bell's other extraordinary inventions: the first transmission of sound over light waves, metal detector, first practical phonograph, and early airplanes, including the first to fly in Canada. He also examines Bell's humanitarian efforts, including support for women's suffrage, civil rights, and speeches about what he warned would be a "greenhouse effect" of pollution causing global warming.

Las revoluciones industriales originaron multitud de avances tecnológicos y uno de los más revolucionarios fue la invención del teléfono de masas. Alexander Graham Bell (1847-1922), científico, inventor y logopeda escocés, es mundialmente conocido por contribuir a la popularización de la comunicación telemática. En 1876 patentó el teléfono en Estados Unidos y, a través de su compañía, implantó el teléfono como medio internacional de comunicación de masas.

The biography of the teacher of the deaf who, through his knowledge of music, human speech, and hearing, invented the telephone. Bell was a pioneer in many fields that aided communication over distances. He worked tirelessly to help the deaf communicate with others (even Helen Keller came to him for help). After the telephone, Bell invented the photophone (a device that uses a beam of light to transmit sound wirelessly), and developed phonographic sound recording methods.

A biography of the famed inventor of the phone. We learn the very personal motivation behind his work. We also come to understand that the information comes from the pen of one who made his observations while Bell was still alive - and still inventing. Narrated by Glenn Hascall.

In Vera Rubin: A Life, Jacqueline Mitton and Simon Mitton provide a detailed, accessible overview of Rubin's work, showing how she leveraged immense curiosity, profound intelligence, and novel technologies to help transform our understanding of the cosmos. But Rubin's impact was not limited to her contributions to scientific knowledge. She also helped to transform scientific practice by promoting the careers of women researchers. Not content to be an inspiration, Rubin was a mentor and champion for hiring women faculty and honoring them with awards historically exclusive to men.
