Harald Jensen was born in 1879 in
Aarhus,
Jutland to farmer Niels Georg Oscar Jensen and Clara (
née Nielsen), the latter of whom was purported to be a descendant of the great Danish poet
Bernhard Severin Ingemann. Around 1885 the family migrated to
Queensland, where young Harald attended public schools before winning a scholarship to
Brisbane Boys' Grammar School. In 1898, Jensen was employed at
Clement Wragge's observatory at
Mount Kosciuszko before briefly studying at the
University of Sydney; he took time off from 1900 to 1901 to teach in
Sydney and
North Queensland before returning to his studies in 1902, receiving a
Bachelor of Science specialising in
geology in 1904. He was employed as an assistant demonstrator to
Edgeworth David before becoming the first Macleay fellow of the
Linnean Society of New South Wales in 1905, allowing him to travel extensively in the Pacific, including to
Fiji,
Samoa,
Tonga and
New Zealand. He married Jane Elizabeth Ellen England on 26 September 1906 in Sydney. In 1908 he was awarded a
Doctorate of Science and a university medal, and was employed by the New South Wales Department of Agriculture as a soil scientist, publishing
Soils of New South Wales in 1914. ==Career==
