Ada’s Legacy illustrates the depth and diversity of writers, thinkers, and makers who have been inspired by Ada Lovelace, the English mathematician and writer. The volume, which commemorates the bicentennial of Ada’s birth in December 1815, celebrates Lovelace’s many achievements as well as the impact of her life and work, which reverberated widely since the late nineteenth century. In the 21st century we have seen a resurgence in Lovelace scholarship, thanks to the growth of interdisciplinary thinking and the expanding influence of women in science, technology, engineering and mathematics. Ada’s Legacy is a unique contribution to this scholarship, thanks to its combination of papers on Ada’s collaboration with Charles Babbage, Ada’s position in the Victorian and Steampunk literary genres, Ada’s representation in and inspiration of contemporary art and comics, and Ada’s continued relevance in discussions around gender and technology in the digital age. With the 200th anniversary of Ada Lovelace’s birth on December 10, 2015, we believe that the timing is perfect to publish this collection of papers. Because of its broad focus on subjects that reach far beyond the life and work of Ada herself, Ada’s Legacy will appeal to readers who are curious about Ada’s enduring importance in computing and the wider world.

Uses excerpts from letters, memoirs, and documents to recreate the life of Ada Byron, daughter of the English poet, and discusses her contributions to mathematics and her friendships with the leading mathematicians of the period

This is Ada. Although she might look like an ordinary little girl, she’s about to change the world. Augusta Ada Byron, better known as Ada Lovelace, is an inquisitive child. Like her clever mother, she loves solving problems—big problems, little problems, and tricky, complicated problems. Ada invents crazy contraptions and reads all the books in the library of her father, the poet Lord Byron; but most of all she loves to solve mathematical problems. Together with her teacher, the mathematician Charles Babbage, Ada invents the world’s first computer program. Her achievements made her a pioneer for women in the sciences. Zoë Tucker’s words capture the adventurous life of Ada succinctly, and debut picture book illustrator Rachel Katstaller’s art infuses Victorian London with humor. "An impressively balanced mix of engaging description and important facts with a quick explanation of the gender politics of the time and information about Ada's legacy...Inspiring, feminist, and informative in equal parts." –Kirkus Reviews

“[Ada Lovelace], like Steve Jobs, stands at the intersection of arts and technology."—Walter Isaacson, author of The Innovators Over 150 years after her death, a widely-used scientific computer program was named “Ada,” after Ada Lovelace, the only legitimate daughter of the eighteenth century’s version of a rock star, Lord Byron. Why? Because, after computer pioneers such as Alan Turing began to rediscover her, it slowly became apparent that she had been a key but overlooked figure in the invention of the computer. In Ada Lovelace, James Essinger makes the case that the computer age could have started two centuries ago if Lovelace’s contemporaries had recognized her research and fully grasped its implications. It’s a remarkable tale, starting with the outrageous behavior of her father, which made Ada instantly famous upon birth. Ada would go on to overcome numerous obstacles to obtain a level of education typically forbidden to women of her day. She would eventually join forces with Charles Babbage, generally credited with inventing the computer, although as Essinger makes clear, Babbage couldn’t have done it without Lovelace. Indeed, Lovelace wrote what is today considered the world’s first computer program—despite opposition that the principles of science were “beyond the strength of a woman’s physical power of application.” Based on ten years of research and filled with fascinating characters and observations of the period, not to mention numerous illustrations, Essinger tells Ada’s fascinating story in unprecedented detail to absorbing and inspiring effect.

From the 2017 John W. Campbell Award Winner for Best Writer, Ada Palmer's Perhaps the Stars is the final book of the Hugo Award-shortlisted Terra Ignota series. World Peace turns into global civil war. In the future, the leaders of Hive nations—nations without fixed location—clandestinely committed nefarious deeds in order to maintain an outward semblance of utopian stability. But the facade could only last so long. The comforts of effortless global travel and worldwide abundance may have tempered humanity's darkest inclinations, but conflict remains deeply rooted in the human psyche. All it needed was a catalyst, in form of special little boy to ignite half a millennium of repressed chaos. Now, war spreads throughout the globe, splintering old alliances and awakening sleeping enmities. All transportation systems are in ruins, causing the tyranny of distance to fracture a long-united Earth and threaten to obliterate everything the Hive system built. With the arch-criminal Mycroft nowhere to be found, his successor, Ninth Anonymous, must not only chronicle the discord of war, but attempt to restore order in a world spiraling closer to irreparable ruin. The fate of a broken society hangs in the balance. Is the key to salvation to remain Earth-bound or, perhaps, to start anew throughout the far reaches of the stars?
