Samuel Stephens (1808 – 18 January 1840) was an English businessman who was the first Colonial Manager appointed by the South Australian Company to the new colony of South Australia.
He was born the eighth son of Rev. John Stephens (1772-1841) who was prominent in the Wesleyan Methodist Missionary Society and was President of the British Wesleyan Conference in 1827. His siblings included John (1806-1850) and Edward (1811-1861), both of whom were to be prominent in the settlement of South Australia. A quarrelsome individual, he fell out with the Wesleyan authorities in 1835 and applied for a position as an assistant surveyor in the proposed new colony of South Australia. Instead, however, he ended up being appointed the first manager of the South Australian Company.
He travelled to South Australia in February 1836 in the Duke of York (the first of the Company ships, followed by the Lady Mary Pelham, and the John Pirie) with 8 fellow-colonists and 29 labourers, and on 27 July 1836 was the first of the adult colonists to embark on Kangaroo Island, the intended site of the first settlement. The capital of the island, originally to be called "Angas" for the Company's chairman, was renamed Kingscote by Stephens.
The first wedding in the new Province was between Mary Powell a passenger aboard the "John Pirie", and William Staple a member of the ship's crew, and this was performed on 28 August 1836 at Kingscote aboard the John Pirie, by its Captain George Martin. The second marriage in the colony was between Samuel Stephens aged 30 and fellow passenger Charlotte Hudson Beare (c. 1782 – 16 December 1875) aged 53 and this event also took place aboard the "John Pirie" and was performed by Captain George Martin on 24 September 1836. The age difference between the bride and groom caused much gossip. His brother-in-law Thomas Hudson Beare (died 7 November 1861), who travelled with him, was the first storekeeper of the Colony, and father of Professor Thomas Hudson Beare.
Some accounts depict Stephens as an intemperate and inept manager tardy in administrative duties, and exceeding his authority. Suspended after he allegedly attempted to kill a sailor from a rival whaling firm at Encounter Bay, these charges were eventually dismissed due to lack of evidence. He was heavily criticised for the purchase, contrary to instructions, of 60 acres of town land for the South Australian Company, although many later came to applaud his action. Under pressure of being sacked, and well before the expiration of his contract of seven years, Stephens resigned his position in 1837 to be replaced by David McLaren.
