Breweries were among the earliest businesses established after the settlement of Nelson began in 1842. Poalo and Pelham were the first, in October 1843, quickly followed by Hooper & Co. on the corner of Hardy and Tasman Streets. Poalo and Pelham lasted only a few months and their Nelson Brewery trading name was later taken by Hooper & Co. It was in this company that the seeds for the current Founders Brewery were sown.
Joseph Dodson [Harry’s grandfather] was a clever English businessman who, within days of arriving in Nelson in 1854, bought into Hooper & Co. A year later he helped set up the Raglan Brewery and then leased the Bridge Street Brewery from Charles Harley.
Henry Dodson [Harry’s father] joined his father [Joseph Dodson] in brewing in 1879 and after George Hooper's death they changed the company name to J R Dodson and Son.
Henry Duncan, son of Joseph Dodson's daughter Mary-Ann, joined his uncle and grandfather in 1888. He subsequently studied brewing in Great Britain, Denmark and Germany. When Joseph Dodson died in 1890, Henry Duncan and Henry Dodson [Harry’s father] continued to run the firm until Henry Dodson's early death in 1894.
Henry Duncan had inherited his grandfather's business sense, and in 1901 bought the entire company and began an extensive upgrade. He also took on his cousin Harry Dodson, and expanded into aerated waters and cordials.
