Gregor McGregor (18 October 1848 – 13 August 1914) was an Australian politician who served as a Senator for South Australia from 1901 until his death in 1914, representing the Labor Party. He was the party's inaugural Senate leader, and served three terms as Leader of the Government in the Senate. Early life McGregor was born on 18 October 1848 in Kilmun, Argyll, Scotland. He was the son of Jane and Malcolm McGregor. His father was a gardener, and in 1854 the family moved to County Tyrone, Ireland, where he became the chief gardener to Sir Gerald Aylmer (one of the Aylmer baronets). McGregor left school at a young age to join his father. He later spent two years working as an agricultural labourer in England, and then returned to Scotland to work in the Glasgow shipyards. In 1877, McGregor immigrated to South Australia. He initially worked as an agricultural labourer, and for a period he was employed by Richard Baker, one of his future Senate colleagues. In 1885, McGregor moved to Victoria and found work as a stonemason. He returned to South Australia in 1891 and continued working in the construction industry. He was active in the United Builders' Labourers Society, and in 1892 was elected to the United Trades and Labour Council of South Australia. He also became a justice of the peace. Early political involvement In 1893, McGregor became president of the United Political Labor League, a forerunner of the modern Labor Party. He was elected to the South Australian Legislative Council the following year, becoming one of the first members of his party in any Australian parliament. In the Legislative Council, McGregor advocated for new workers' rights, but was also known for his opposition to South Australian involvement in the Boer War and as "a fervent protectionist who espoused the sanctity of White Australia". Senate At the inaugural 1901 federal election, McGregor was elected to the Senate as one of six South Australian senators, and the only one from the Labor Party. He was the final senator to be elected, recording only 644 more votes than his nearest opponent, Andrew Kirkpatrick. However, when he was re-elected in 1903 and 1910 he topped the poll, winning more votes than any other South Australian candidate. When the Labor caucus met for the first time after the 1901 election, McGregor was elected as the party's inaugural Senate leader. His
