Alan MacMasters (20 March 1865 – 25 December 1927) was a Scottish scientist.
He is credited with creating the first electric bread toaster, which then went on to be developed by Crompton, Stephen J.
Cook & Company as the Eclipse.
Although not ultimately a commercial success, MacMasters's invention would pave the way for Charles Strite to invent the automatic pop-up toaster in 1919, which is the device we know as the toaster today.
MacMasters died of heart failure on 25 December 1927 at the age of 62.
In November 2018, the Bank of England shortlisted Alan MacMasters out of 227,299 nominations to appear on the new £50 note, in recognition of his contribution to engineering and science in the United Kingdom.
