Paul Edwin Bielenberg Sorensen (1891–1983) was a Danish-born Australian landscape gardener and nurseryman. After leaving Europe due to the outbreak of the First World War, Sorensen lived in Australia for the rest of his life, mostly in the Blue Mountains. He designed and planted over 100 gardens, of which the best known is "Everglades", in Leura, Australia. Early life Paul Sorensen was born on 16 December 1891 at Frederiksberg, a town now part of the urban area of Copenhagen, Denmark, which is the site of two extensive public gardens, Frederiksberg Gardens and Søndermarken. Sorensen was employed at a Copenhagen nursery, Hørsholm Planteskole, at the age of thirteen. He enrolled at the Hørsholm Tekniske Skole to study horticulture. For the last two years of this training, Sorensen was under the direction of Lars Nielsen, a leading horticulturist, who at that time was responsible for the design of much of the open spaces of Copenhagen. During that same period, Sorensen did garden maintenance work at Hvidøre, which at that time was a summer residence owned by King Christian IX's daughters, Queen Alexandra of the United Kingdom and Dowager Empress Maria Feodorovna of Russia. After performing national service, he worked in Germany, France, and Switzerland. He was employed by the landscape designers and contractors Mertens Bros. Sorensen was later to state that it was the outbreak of the First World War (although his homeland Denmark was neutral) that motivated him to migrate to Australia, when he saw his French, German, Austrian, and Italian friends in Switzerland being recalled to their homelands for military service. Career in Australia Sorensen arrived in Australia in 1915. He initially found employment as a farmhand in Victoria, prior to getting work at Ormond Plant Farm propagating ferns. He moved to the Blue Mountains and obtained work as a gardener at the Carrington Hotel at Katoomba. He opened a plant nursery, called Sorensen's Nursery, at Katoomba, before moving the business in 1920 to Leura, a nearby mountain village that would become his lifelong home. Initially maintaining existing gardens, Sorensen was soon planting large gardens for wealthy people who had homes in the Blue Mountains. During the 1920s, he created gardens in the area for the residences "Sylvan Mists", "Gabo", "La Vista" at Wentworth Falls, "Dean [or Dene] Park", and "Cheppen". Sorensen assisted Lady Fairfax, the widow of the Sydney newspaper magnate Sir James Oswald Fairfax (1863–1928), with the garden
