The History of Numero®

The creator of Numero®, Rev. Frank Drysdale (1932-2011), was forced into early retirement in 1989 when he was diagnosed with Alzheimer’s disease. Frank’s own remedy to this situation was to keep himself mentally fit by playing mind games, many of which involved cards. He enlisted the help of his young grandchildren to help him pass the time playing different card games.

Rev Frank DrysdaleNumero® was developed as a product of these sessions with his grandchildren, as Frank started with a simple concept and developed it into the game we now call Numero®.

Numero® was demonstrated in public for the first time in 1993 when presented at the Mathematics Association of Western Australia annual conference. The reception it received prompted Frank and his wife Joan to print 2000 packs of Numero® which were collated and packaged in Frank’s back shed by a band of willing helpers. Numero® had been born and Frank and Joan Drysdale were kept busy holding workshops and collating and packing Numero® until, 40000 packs later, it grew to a stage where in 1998 they were introduced to R.I.C. Publications, an international educational publisher based in their home state of Western Australia.

Working closely with Frank and Joan, R.I.C. Publications further developed the presentation of the game and started to spread the news to other parts of Australia and the world. Numero® is now sold in many countries throughout the world, to children and adults alike. It continues to grow in popularity, spreading to more and more countries, and gaining enthusiastic endorsement from educators and players alike.

From the very beginning, the ownership of copyright of Numero® was given to Alzheimer’s Australia WA by Frank and Joan Drysdale. This means that royalties provided from the sale of every pack of Numero® are now channelled to the Drysdale Family Charitable Foundation Trust, which provides money to fund various dementia-related programs throughout the world.

Drysdale Family Charitable Foundation Trust
ABN: 736 969 213

The Drysdale Family Charitable Foundation Trust (herein referred to as the ‘Trust’) was formed in 1999 to manage proceeds from sales of Numero® in the form of royalties. Numero®, which was invented by Rev. Frank Drysdale, himself an Alzheimer’s disease sufferer, is now sold through a number of distributors in Asia, Europe, the Americas, New Zealand and Australia. Part of the proceeds raised from the sale of Numero® in countries outside of Australia will be channelled back to the country where the funds were generated to fund projects conducted by/through the Alzheimer’s association(s) of that country.

The Trust received its endorsement as a tax deductible gift recipient from the Australian Taxation Officer in 2001, by which donations above $2(Aud) are tax deductible within Australia.

The Trust is managed by a board of management, which comprises the Executive Committee of the Alzheimer’s Disease and Related Disorders Association of Western Australia, Inc. (trading as ‘Alzheimer’s Australia WA’). The Chairman of the Board of Management is Mr Craig Masarei, a lawyer by training, working as a risk manager.
