The widow of campaigner Tony Nicklinson will take part in a conference as part of a proposal to legalise assisted suicide.
Jane Nicklinson is appearing in Edinburgh with right-to-die supporter and politician Margo MacDonald, who hopes to make Scotland the first part of the UK to change the law.
Ludwig Minelli, founder of Swiss assisted dying organisation Dignitas, is also due to contribute.
Mr Nicklinson died in August days after he lost his High Court battle in England for the right to end his life.
The 47-year-old, who refused food in the days following the landmark case, was paralysed by a stroke in 2005.
Ms MacDonald, an Independent MSP at Holyrood who has Parkinson's disease, hopes to persuade the Scottish Parliament to back her revised legislation, having already tried and failed to change the law under the last minority SNP administration.
"This is a very apt moment to stage what I think is the first ever meeting of its type in Scotland," she said.
"It's generally known that we are in the process of producing a Bill which represents our second attempt to change the law in Scotland so that assisting someone to commit suicide would no longer be a crime.
"The Bill we envisage will be slightly different from some of the other jurisdictions. For example, we visualise its use by people suffering from irrecoverable conditions for whom life has become intolerable, like Tony Nicklinson for example. This is where the conference will be especially useful to us and it will be very instructive for us to hear how those attending the conference feel about this and other aspects of our proposal."
Other contributors at the conference are Sir Graeme Catto, chairman of Dignity in Dying and emeritus professor of medicine at the University of Aberdeen, and Dr Libby Wilson, convener and medical director of support group Friends at the End.
