On the 100th anniversary of David Lloyd George becoming Prime Minister, his family are launching an appeal to celebrate his achievements.
He was one of the 20th century's most famous radicals as well as being the first and only Welshman to hold the office of Prime Minister.
The Lloyd George Premiership Centenary Appeal aims to raise £250,000 to help develop the museum dedicated to him in Llanystumdwy.
TV historian and great-great-grandson Dan Snow is backing the campaign to keep his legacy alive and refurbish the museum.
Former solicitor Lloyd George went on to lead the coalition government through the First World War.
As well as playing a key role in the Paris Peace Conference of 1919 that helped to re-shape Europe.
His grand niece Elizabeth George, from Criccieth, says she hopes the fundraising will see more modern and interactive exhibits.
