Short answers, pulled from the story.
Henry Fourdrinier entered the world on the 11th of February 1766. He was born into a family deeply embedded in the paper trade where his father worked as both a paper maker and a stationer.
Sealy Fourdrinier joined his brother in commissioning a revolutionary machine design. They sought out Louis-Nicolas Robert for his innovative concept capable of producing continuous rolls of paper.
A patent was granted on the 24th of July 1806 by Repertory of Patent Inventions. London published details in 1807 describing a machine making long continuous webs of paper.
The invention cost £60000 to develop fully which caused the brothers to go bankrupt immediately after success. Competitors adopted the technology freely while the brothers received no royalties from thousands of machines built.
No money was ever paid to him for the two machines constructed in Peterhof Russia during 1814. The international deal collapsed under political indifference despite Henry petitioning Tsar Nicholas repeatedly to honor the agreement.
Parliament approved a payment of £7000 in 1840 following a petition reached in 1839 seeking redress for unpaid debts. This final settlement arrived long after their initial bankruptcy before Henry lived until the 3rd of September 1854 at age 88.
