Dom's Fund will pay for research at the University of East Anglia

Dominic Barker, who was aged 26, from Holbrook in Suffolk, took his own life on 30 September 1994.

Dominic's father, Alan, said his son had two degrees but people focused on his stammer and not his ability.

In 1998, Dominic's parents set up Dom's Trust, in remembrance of their son. The trust will now fund research at the University of East Anglia in Norfolk.

Mr Barker said: "The problem that people who stammer face is that although they understand perfectly well what is being said to them the difficulty is in articulating the words and getting them out.

"This leads to frustration and disappointment.

Listen to people, give them time to express themselves, don't say words for them and show that you are interested Alan Barker

"Within the family it was a fact of life and not a problem but externally he (Dominic) felt that no matter how able he was people concentrated on his stammer rather than his own abilities."

Dominic had degrees in agriculture and economics from Aberdeen and Reading universities and was keen to start a career in agriculture.

Mr Barker said he hoped the trust would promote understanding of people with a stammer.

"Listen to people, give them time to express themselves, don't say words for them and show that your are interested," he advised.

Dom's Fund paid for research at Suffolk College and is now funding a PhD at the University of East Anglia into stammering.
