The leading manufacturing firms in the Irish Free State in 1929

The manufacturing sector of the 1920s Irish Free State was substantially more complex in structure than occasional references to a ‘beer and biscuits’ economy suggest. There were nine factories employing 500 workers or more in 1929, while the larger firms in sectors such as bacon curing, flour milling and fertilisers each operated more than a single factory. This article identifies the largest manufacturing firms and establishments of the era, as well as the largest within each industrial sector. Twenty-two firms had workforces of a minimum of around 400. Three of the five largest were foreign subsidiaries, the most significant of which – the Ford Motor Company – employed, at one stage, more than twice as many workers as Guinness. Of the larger indigenous companies, the majority were Protestant-owned, though Catholic-owned firms dominated in certain industrial segments.
