Brown & Polson introduce corn flour to Britain
Brown & Polson was established when starch manufacturers John Polson (1800 – 1843), William Polson (1810 – 1893) and John Brown (1806 -1889) merged their interests in 1842. The factory was at Thrushcraigs in Paisley, Scotland.

Brown & Polson had been appointed starch manufacturer to Queen Victoria by 1853.

John Polson Jr (1825 – 1900) discovered a method for manufacturing pure starch from maize, which he called corn flour. He patented the process in 1854. It was the first corn flour to be manufactured in Britain.


Advertised as a substitute for arrowroot, corn flour was used as a thickening agent for foods, and used to make custard, blancmange, puddings and cakes.

Production was relocated to the Royal Starch Works at Carriagehill, Paisley from 1857. The Thurscraig works were divested.

William Polson left the partnership to enter into starch manufacture independently from 1857.

In a major promotional coup for the business, the influential Dr Hassall confirmed the purity of Brown & Polson corn flour in 1858.

Brown & Polson employed 32 men and 60 women in 1861.

Brown & Polson employed around 200 people by 1871. The business introduced a profit-sharing scheme for its workforce from 1873.

By 1879 the partners were John Polson Jr, John Brown and John Armour Brown (1839 – 1924).

John Polson Jr was a practical and thrifty man, as well as a generous benefactor.

Brown & Polson was considered an enlightened employer. The firm was proud to announce in 1893 that a worker had never encountered the loss of a life or a limb in their factories, and the workforce had never gone on strike.

  1. I’m directly descended from William Brown of Brown & Polson, through my late paternal grandfather, Dr. John Brown MBE of Bedlington, Northumberland. Family legend has it that his father had some sort of dispute with the family and moved to the North East to start a new life on his own without the support of the family. When I was a child, my father took me to visit some of my relatives from that side of the family in Dumfries, but that is the only contact that I have ever had. If anyone knows anything about the Browns of Brown and Polson and the other descendants, I would love to know for the purposes of my own family research. You can find information on my late grandfather here:

    Kind regards,

    Ian Brown

  2. members of my family all worked at the starch works from Thrushcraigs to Falside road from the 1850’s

    I have a photo of my great grandfathers retirement from Brown and Polson’s. and a large Children’s Christmas Party

    My great grandfather and then my grandfather rented a works house in Falside road. My father grew up at 99 and in in the 90’s my brother met and married a woman he worked with in CPC and they moved into a Brown and Polson’s house then owned by the local authority, they now own it.

    I would like to know if you can say where all the Archives for Brown and Polson’s finish up.

    1. Hi Izzy
      Did you ever find out where Brown&Polson archives were held? The reason I ask is that I have a large collection of their memorabilia. I originate from Paisley and my wife worked in the sales office in the late 70’s early 80’s
