In the early 1840s he embarked on experiments to make starch from Indian corn, and after much trial and error he succeeded. He could not interest his employers or any other starch makers in his ideas. In 1846, he ended his connection with William Colgate & Co, and he and his son, Thomson, established T. Kingsford and Son at Bergen, N.J., later to be joined by partners. He did not patent his process, and it was kept as a secret within the family.
