Manuscripts
The archive extends over six decades, from 1803 to 1869. Included in the archive are letters and manuscripts covering William Congreve's career in rocketry. The most notable of these is his diary of the 1807 Copenhagen bombardment, which represents the first truly successful large-scale use of the Congreve war rocket in combat. Other noteworthy manuscripts include a signed draft and a fair copy of a "Report to the Commissioners of the Navy" dated October 1813, in which Congreve summarized his war rocketry activities from 1805 to 1813; a letter dated November 1813 relating to "the expense, or rather the economy of the Rocket System"; bills for materials used in rocket construction; an undated letter to a Captain Elliot discussing the subject of a "rocket cavalry"; letters discussing a plan of "applying Rockets for throwing ropes ashore from shipwrecked vessels"; and letters in which Congreve writes of his achievements and his attitude towards his work. The archive also contains manuscripts and letters relating to some of Congreve's other inventions: naval guns, bombships, and Congreve's design for a paddlewheel boat, which is detailed in a long letter illustrated with Congreve's sketches. Also included are a long series of love letters that Congreve wrote to his wife, Isabella, and another series of long, detailed letters written to Congreve during the last few months of his life by his secretary, R. Drake, discussing, among other things, Congreve's political career as a Member of Parliament, his precarious financial position, the publication of his Treatise on the General Principles, Powers, and Facility of Application of the Congreve Rocket System (1827), and negotiations with the British East India Company for exclusive rights to the Congreve war rocket for use in India. Included in the remainder of the archive is a letter from Congreve's father, William Congreve Sr., to Sir Joseph Banks (1743-1820), president of the Royal Society, discussing the elder Congreve's responsibilities at the Royal Arsenal in Woolwich. Another series of letters, some written by Congreve, concern a will of which Congreve's aunt, Miss Mary Congreve, was the executrix. There are numerous letters written by Isabella Congreve after Congreve's death in 1828, mostly on financial matters-- Congreve's affairs were left somewhat embarrassed upon his death, and the archive includes several records of bills and promissory notes, both paid and owing. Lastly, there are several letters presumably written by Congreve's descendants, the last dated Feb. 1, 1869.
