Johann Christian Heussler was born at Bockenheim, Frankfurt, Germany on 15 June 1820. He was educated at the state school, and was subsequently a student at a French institution at Bockenheim, and Dr. Jeiteles's Mercantile Institute at Frankfurt. He entered in business as a wine merchant at Frankfurt, and later on, while still young, received an important appointment in a mercantile firm in Holland, representing the firm at the London Exhibition in 1851. He emigrated to Australia in 1852, and established a business, in partnership with others, in Melbourne.
Business interests
Due to poor health he moved to Brisbane 1854 and established the mercantile firm Heussler and Co. Over two decades Heussler became a highly respected business man and citizen of Queensland. He was recognised as a founding member of the Queensland Club, Consul for the Netherlands, German Consul, and Emigration Agent for German shipping companies.
In May 1860 Heusller purchased a portion of land high on a hill on what was most likely undeveloped natural bushland. He purchased the adjoining Portion 291 two years later in partnership with George Reinhard Francksen. In 1864 Francksen died and the land passed to Heussler. Heussler is believed to have built his home Fernberg on that land in 1865, giving it a name of German origin that meant "distant mountain". The design of the house is attributed to Benjamin Backhouse, an architect responsible for several substantial commissions in Queensland, New South Wales and Victoria. Local examples of his work include other villa residences such as Baroona, Cintra House, Riversleigh for Edward Tufnell and Old Bishopsbourne. Due to financial difficulties, Heussler was forced to leave the property in 1872 and for the next five years Fernberg was leased. In November 1877 the estate was advertised for sale. The house and grounds were described as being:
"Built of brick and stone, being four stories high, having below kitchen and servants' room; on the ground floor spacious drawing, dining, and breakfast rooms; on the first floor three large bedrooms, and one large room on the second floor. The roof is covered with slates, the verandahs and balconies being spacious, and presenting a delightful retreat for the enjoyment of pure air, shade and widespread and charming view. The grounds are all enclosed, the timber having been thinned so to give the place a park-like appearance, and there is a shrubbery and garden around the house."
John Heussler died on Saturday 26 October 1907 at his home Unthank at Christian Street, Albion. His funeral moved from his home to the Toowong Cemetery.
