San Francisco in April 1865, but disagreements between its leaders meant that little was achieved. The party moved north to Vancouver where Kennicott suffered a period of ill health. After his recovery they moved north again to Alaska in August 1865. Kennicott died in May 1866 while traveling up the Yukon River. In an interesting twist, the scientist became the subject of study. Smithsonian Institution scientists researched his cause of death from 2001-2016. The resulting study suggests the cause of death was cardiac arrest. Kennicott appeared to have suffered from long QT syndrome, which was only made worse by strychnine, a drug that Kennicott regularly self-administered to improve his condition but which only aggravated it. According to the Washington Post's report, "The combination of stress, physical exhaustion and toxic "medicine" was too much for the young scientist's weak heart." With permission of his modern-day family, his body has been added to the human anatomy collection at the Smithsonian. Legacy Kennicott's body was returned to his family's home in Illinois nearly circumnavigating the globe over the course of a year, being enclosed in a metal canister and shipped to Russia and Japan rather than sent back on undeveloped trails through Canada. Meanwhile, Secretary of State William H. Seward purchased Alaska from Russia with a treaty signed on March 30, 1867. To commemorate his efforts on behalf of science, Kennicott Glacier, Kennicott Valley, MV Kennicott, and the Kennicott River were named after him. The town of Kennecott, famous for rich copper mines, was named for its proximity to the glacier. However, the name was slightly misspelled. Natural features have retained the original spelling of his name, while the mines and related businesses have continued to use this alternate spelling. Additionally, two birds retain Kennicott's name: the western screech owl (Megascops kennicottii ) and the Alaskan Arctic Warbler (Phylloscopus borealis kennicottii ). Some of his papers are maintained at Northwestern University, others at his family home, The Grove, a National Historic Landmark in Glenview, Illinois, where his original grave remains in a family plot. His papers are also available on microfilm at the Glenview Public Library in the Genealogy & Local History Room. A 3-D reconstruction of his face has been done by the Smithsonian Institution, by scanning his skull and using computers to reconstruct his facial structure. A 3-D copy of the skull was then made, onto which a sculptor molded clay
