On October 2, 1816, a two-masted brig flying the colors of the Russian Imperial Navy arrived in the San Francisco Bay. Named the Rurik for a Viking explorer of Russia, the ship had rounded Cape Horn and explored islands in the South Pacific during its fifteen months at sea. On board were four scientists--including Adelbert von Chamisso, a naturalist, linguist, botanist, and romantic writer. Throughout the month of October, Adelbert von Chamisso compiled an inventory of many plant and animal species in the bay area. Chamisso is best known locally for giving a Latin name to the California poppy, Eschscholzia californica, which he described based on specimens found at the Presidio. He named the poppy in honor of his friend Johann Friedrich Eschscholtz, the Rurik's young surgeon and also a botanist. Eschscholtz returned the compliment by naming a local lupine species for Chamisso, Lupinus chamissonis.
Following her time in the San Francisco Bay, the Rurik returned to St. Petersburg in 1818--having long since been given up for lost. Later that year, Adelbert von Chamisso was named custodian of the botanical gardens in Berlin. He remained active in science for the remainder of his life, pursuing investigations in fields as diverse as zoology and Australasian languages. To this day, Chamisso's Gesammelte Werke (Gathered Works) is esteemed for its distinctive record of California natural history. On December 12, 1890, the California State Floral Society selected Eschscholzia californica the state flower.
