Frederick Whittaker Dixon (1854–1935) was an architect practicing in Oldham, Greater Manchester. He worked for the partnership Potts, Pickup & Dixon from 1880 to around 1890 when he set up his own practice. All three men were Methodists. He built 22 cotton mills in Oldham, and more in Europe. The Oldham mills contained 1.8 million spindles, making him responsible for about 30% of capacity increase at that time.
His early mills were recognisable by the heavy use of yellow brick to decorate the facades. His later mills used a motive of pronounced piers or buttresses between the windows, they extended unbroken from the ground to the parapet. The water tower designs were varied, drawing inspiration from many architectural styles. He also designed chapels such as the one for the Swedenborgians in Failsworth and the Primitive Methodists in Chadderton.
