Medical Practice and Provincial Politics
Originally trained as a surgeon, Stephen Lunn Muller arrived in Nelson in 1850 aboard the New Zealand Company ship Pekin.1 Repurposing surplus pages from the ship's official logbook, he maintained daily records of patients and medical prescriptions in Latin between March 1852 and June 1856.2 In December 1851, he married widow Mary Anne Wilson, establishing their first family home in the Wellington region.3
Muller gradually transitioned from active medical practice into public administration and colonial politics, reflecting a common career path for educated professionals in early New Zealand.4 He served as official provincial meteorologist and won election to the Nelson Provincial Council, representing Waimea East from 1855 to 1857 and Amuri in 1857.5 His administrative diligence during these formative legislative sessions established his reputation as a capable civil servant.6
In 1857, Crown authorities appointed Muller as Resident Magistrate for the Wairau district, prompting his permanent relocation to Blenheim.7 Assuming office during a period of rapid pastoral expansion, he presided over the local court, resolving civil land disputes, commercial disagreements, and criminal proceedings.8
Colonial Orthodoxy and Domestic Politics
Dr Muller fulfilled his judicial duties with rigid efficiency, earning respect across the province as an unyielding representative of British law.9 His personal worldview remained firmly rooted in Victorian social orthodoxy, holding that women belonged strictly within the domestic sphere and ought not to participate in political affairs.10
While Muller enforced public justice from the bench, his wife Mary Anne secretly authored New Zealand's foundational feminist arguments from their shared home.11 To avoid domestic conflict and shield her husband's judicial standing, she published under the pseudonym 'Fémmina', penning her landmark 1869 pamphlet An Appeal to the Men of New Zealand.12 Their household formed a striking historical paradox, harbouring both conservative Crown authority and covert democratic agitation.13
Muller remained entirely unaware that his wife was conducting targeted lobbying with Premier William Fox and corresponding with international philosophers.14 Her covert writing directly influenced the passage of the Married Women's Property Acts, securing financial rights for wives while her husband continued enforcing colonial statutes.15
Frontier Justice, Retirement, and Death
Reflecting on early Blenheim during his later years, Muller recalled a turbulent frontier settlement where lawlessness was common and local agitators once pulled down the town lock-up.16 Through persistent judicial oversight and cooperation with early police forces, his bench gradually established civil order as Marlborough grew.17
Although earlier accounts suggested he retired in 1871, official government records confirm Muller served continuously until December 1878.18 His bench tenure ended when the central government mandated a compulsory retirement to amalgamate regional judicial offices.19 At a special court assembly on 30 December 1878, senior barrister Mr Conolly and assembled local magistrates expressed deep regret over his forced departure, while Muller publicly stated he remained fully competent in mind and body.20
Muller spent his remaining years in quiet retirement at his Blenheim estate, New Amersfoort.21 He passed away there on 26 March 1891 at seventy-six years of age.22 His death preceded that of his wife by a decade, after which Mary Anne's identity as 'Fémmina' was publicly revealed, cementing both their names in Marlborough's colonial history.23
