Lilly began raising funds to build the Indiana Soldiers' and Sailors' Monument. Construction began in 1888, but the monument was not completed until 1901, three years after Lilly's death. The interior of the monument houses a civil war museum, established in 1918, that is named in Lilly's honor. Colonel Lilly's main residence was a large home in Indianapolis on Tennessee Street (renamed Capitol Street in 1895), where he spent most of his time. Lilly, an avid fisherman, built a family vacation cottage on Lake Wawasee near Syracuse, Indiana, in 1886–87. He had enjoyed regular vacations and recreation at the lake since the early 1880s. Lilly also founded the Wawasee Golf Club in 1891. Lilly's lakeside property became a haven for the family. His son, Josiah, built his own cottage on the estate in the mid-1930s. Lilly developed cancer in 1897 and died in his Indianapolis home on June 6, 1898. His funeral was held on June 9 and attended by thousands. His remains are interred in a large mausoleum at Indianapolis's Crown Hill Cemetery. Legacy At the time of Lilly's death in 1898, his company had a product line of 2,005 items and annual sales of more than $300,000 ($ in 2020 chained dollars). His son, Josiah, inherited the company following his father's death, and became its president in 1898. Josiah continued to expand its operations before passing it on to his own sons, Eli Jr. and Josiah Jr. (Joe). Lilly's son and two grandsons, as well as the Lilly company, continued the philanthropic efforts that Lilly practiced. Eli Lilly and Company played an important role in delivering medicine to the victims of the devastating 1906 San Francisco earthquake. In 1937 Lilly's son and grandsons established the Lilly Endowment, which became the largest philanthropic endowment in the world in terms of assets and charitable giving in 1998. (Other endowments have since surpassed it, but it still remains among the top ten.) Lilly's firm grew into one of the largest pharmaceutical companies in the world. Under the leadership of Lilly's son, Josiah (J. K.) and two grandsons, Eli and Joe, it developed many new innovations, including the pioneering and development of insulin during the 1920s, the mass production of penicillin during the 1940s, and the promotion of advancements in mass-produced medicines. Innovation continued at the company after it was made a publicly traded corporation in 1952; it developed Humulin, Merthiolate, Prozac,
