The Kiwi inventor of the hamburger holder known as a "doofer" is battling multiple sclerosis, and is raising money for stem cell treatment in Russia.
Roland Matthews, 47, has secondary progressive multiple sclerosis, and a Givealittle page has been started to raise money so he get treatment in Moscow.
In the description for the page, Matthews' family say he requires expensive treatment for a "better future" with his wife Andrea and 5-year-old daughter Isabella. So far $32,150 has been donated by 58 people.
"He can no longer, because of the many physical consequences of the disease, take part in even simple family pleasures such as taking Isabella to school, swimming lessons and walking the dogs."
Matthews is described as having worked for Fisher and Paykel and Talbot Technologies, and holds the patent for the "doofer" hamburger holder. The doofer is a cardboard cut out that folds together to make a hamburger holder and stop burger toppings from sliding out.
