INDUSTRIALIST John Booth, former chairman and managing director of building group Hepworth, left more than £2,206,000 in his will.
Mr Booth, of Hazlehead, near Penistone, died in March at the age of 90.
His home was close to the firm's huge site at Crow Edge.
Mr Booth was well known for his work in connection with the clay pipe and ceramics industry, in particular with his involvement with the public company that evolved from the private family firm of Hepworth Iron.
Mr Booth was responsible for developing the roller kiln method of producing clay piping.
More importantly, he ensured the process became cost-effective.
That enabled the firm to reach a global market, with exports particularly strong in Europe.
He was renowned as an expert in the ceramics industry.
Mr Booth is survived by his wife, Margaret, four children and eight grandchildren.
He was awarded the MBE for his work.
