The twelfth volume of The Correspondence of John Tyndall contains 326 letters and covers the fifteen months of Tyndall's life from March 1871 through May 1872, a time when he was a central figure in the field and had a substantial reputation in both the UK and the US. It begins just before the publication of Fragments of Science in April and Hours of Exercise in May. It includes a number of small but public disputes about science. Tyndall had a number of visits from friends and dignitaries, and he traveled to Switzerland, Ireland, and the countryside for scrambles. He was dealing with family issues out of Ireland, which were troublesome for him. He was busy administering the Royal Institution and the Royal Society; he was also working as the scientific consultant to Trinity House, which was involved in overseeing lighthouses in the United Kingdom, of which Ireland was a part at this time. Unlike other volumes, this one is not defined as much by one or two major projects or events for Tyndall, but instead includes a number of smaller projects and issues for him personally and professionally. As a leading man of science, and preoccupied with the work required for Trinity House, he had little time for socializing or research and began to refuse both social and professional invitations. Although well established, he remained concerned with his image, which manifests in a number of ways throughout this period.

The 329 letters in this volume represent a period of immense transition in John Tyndall's life. A noticeable spike in his extant correspondence during the early 1850s is linked to his expanding international network, growing reputation as a leading scientific figure in Britain and abroad, and his employment at the Royal Institution. By December 1854, Tyndall had firmly established himself as a significant man of science, complete with an influential position at the center of the British scientific establishment. Tyndall's letters throughout the period covered by this volume provide great insight into how he navigated a complicated course that led him into the upper echelons of the Victorian scientific world. And yet, while Tyndall was no longer as anxious about his scientific future as he was in previous volumes of his correspondence, these letters show a man struggling to come to terms with his newfound status, a struggle that was often reflected in his obsession with maintaining an "inflexible integrity" that guided his actions and deeds.

"John Tyndall was a leading scientific figure in Victorian Britain, who established the physical basis of the greenhouse effect, and why the sky is blue. This rich biography describes the colourful life and achievements of this brilliant communicator, physicist, and mountaineer, who ascended from humble beginnings to the heart of Victorian society."--

John Tyndall (1822–1893) is best known as a leading natural philosopher and trenchant public intellectual of the Victorian age. He discovered the physical basis of the greenhouse effect, explained why the sky is blue, and spoke and wrote controversially on the relationship between science and religion. Few people were aware that he also wrote poetry. The Poetry of John Tyndall contains his 76 extant poems, the majority of which have not been transcribed or published before, and are succinctly annotated in a style similar to that used for the letters published in The Correspondence of John Tyndall.The poems are complemented by an extended introduction, which was written by the three editors together as a multidisciplinary analysis. The essay aims to facilitate readings by a range of people interested in the history of Victorian science and of Victorian science and literature. It explores what the poems can tell us about Tyndall’s self-fashioning, his values and beliefs, and the role of poetry for him and his circle. More broadly, the essay addresses the relationship between the scientific and poetic imaginations, and wider questions of the nature and purpose of poetry in relation to science and religion in the nineteenth century.

The tenth volume of The Correspondence of John Tyndall spans from January 1867 to December 1868. It begins with Tyndall publicly enmeshed in a controversy that revealed his views on race, politics, and justifiable violence. Further pressure is exerted on him personally by the death of his mother Sarah, and the numerous calls on him to support relatives in Ireland. Michael Faraday's death in August 1867 adds to these demands, as Tyndall assumes Faraday's responsibilities at the Royal Institution. In this period, Tyndall writes his popular book Sound, as well as Faraday as a Discoverer, his memorial to Faraday.

Physicist John Tyndall and his contemporaries were at the forefront of developing the cosmology of scientific naturalism during the Victorian period. They rejected all but physical laws as having any impact on the operations of human life and the universe. Contributors focus on the way Tyndall and his correspondents developed their ideas through letters, periodicals and scientific journals and challenge previously held assumptions about who gained authority, and how they attained and defended their position within the scientific community.
