Jacqui Sieger was born during the Second World War in Swanage, Dorset, UK, at which time her father, Joshua Sieger. C.B.E., was a pioneer scientist on the new invention of radar. His role led him towards research for widescreen colour TV, which took him and his family to New York, continuing the research into the new field of colour TV.
It was not until the family returned to their native Dorset ten years later, that Jacqui found she had a natural gift for painting. Fascinated by colour, design and fashion, Jacqui trained at Bournemouth College and went on to be a Trainee Buyer for Derry and Toms in Kensington, London. Strangely, this is where her grandparents had met each other in the sister store, John Barker & Co, in the 1920s, working as Tailors.
With her London training and experience, she was eager to start her own business in the fashion world, Like her grandparents, she made leather fashion goods which led her to move to North Yorkshire, and soon was selling to many leather shops in York, introducing her to all the cloth and woollen mills in the area where she was buying her leather. This led Jacqui to extend her business to horse clothing, and with the help of the Council of Small Industries, was trained as a sadler. Soon, many leading show jumping and horse racing celebrities in the UK and abroad were buying her products. Through this time Jacqui still kept up her oil painting and often sold her paintings to private buyers.
