Cuthbert Eden Heath (1859-1939) was a Lloyd’s underwriter whose innovations transformed the Lloyd’s market from an almost exclusively marine institution into a diversified non-marine and reinsurance market. He is generally credited with the invention of modern excess of loss reinsurance and with directing the Lloyd’s response to the 1906 San Francisco earthquake.

Cuthbert Eden Heath was born in 1859, the son of an admiral. He entered Lloyd’s as an underwriting member in 1880 at the age of twenty-one, having been introduced to the market through family connections. His career at Lloyd’s spanned almost six decades, and he remained active in the market until shortly before his death in 1939.
Heath worked initially in marine insurance, the traditional Lloyd’s business, but quickly moved beyond it. He began accepting non-marine risks - burglary, jewellery, loss of profits and fire insurance - at a time when the market regarded such business as outside its proper sphere. By the early twentieth century the Heath syndicate had become one of the largest at Lloyd’s, and Heath himself was the leading figure in the market’s non-marine expansion.
Heath’s principal contributions were threefold. First, he pioneered the writing of non-marine insurance at Lloyd’s. Burglary insurance, written by Heath from the late 1880s, and an early form of loss-of-profits (business interruption) cover, were among the new classes he introduced. He also led the development of Lloyd’s fire reinsurance business, particularly the reinsurance of United States fire offices.
Second, Heath is credited with the development of modern excess of loss reinsurance. Where earlier reinsurance had been written on a proportional basis, Heath’s wordings attached above a defined retention and responded to losses exceeding that figure. This non-proportional structure became the foundation of the international catastrophe reinsurance market that developed in the twentieth century.
Third, in the aftermath of the San Francisco earthquake and fire of April 1906, Heath sent the celebrated instruction to his US representative: “Pay all of our policyholders in full irrespective of the terms of their policies.” The decision was both a commercial judgement that paying losses fully would secure the Lloyd’s reputation in the United States, and an ethical position taken at a moment when other insurers were contesting cover. The Lloyd’s brand in the US market was substantially built on that response.
Heath’s syndicate evolved over the twentieth century through a number of successor managing agencies. The non-marine market he created accounts for the majority of Lloyd’s gross written premium today; the excess of loss reinsurance structure he pioneered is the standard form of catastrophe reinsurance worldwide; and the “pay in full” tradition associated with the 1906 earthquake remains a touchstone of Lloyd’s marketing and self-image. He was appointed CBE in 1920.
