The great British painter you've never heard of?
The name of Dave Pearson may not come to mind when you think of great British painters of the twentieth century.
But to his admirers, this painter exemplified what it means to be an artist: committed, eccentric, a determined outsider who was obsessed by his work.
Dave Pearson died in July 2008. One of his students, artist Bob Frith has spent the last year restoring his mentor's cluttered and decaying studio.
We came to hear about Bob when he was nominated for an iPM New Year Honour. Reporter Nigel Wrench went to the Rossendale Valley to meet him at that studio.
