                                     Geoff Tootill 

The Chadderton Historical Society is arranging for a Blue Plaque for this remarkable Chadderton born scientist. 

Without the help of Tom Kilburn, Freddie Williams, Geoff Tootill and his fellow professors, working

 at Manchester University over 50 years ago, it is unlikely you would be reading this page today in its present form. 

They were completely unaware that the project they were working on, The Manchester Small Scale Experimental Machine, 

affectionately known as 'the Baby', would become so significant an achievement. 

Before the electronic computer, information technology used to be a very slow process using cables and plug boards.

The research was made possible after the Ministry of Aviation awarded the team a contract to see if the idea of an electronic 

computer was feasible. 

At Monday 21st June, 1948 Geoff and Tom Kilburn knew they'd made history having just witnessed their 

small xperimental machine, affectionately known as Baby, execute a stored computer program to calculate the 

highest factor of a number successfully. 

Between 1948 and 1949 they produced the Manchester Mark 1 and so created the world's first wholly electronic computer. 

The Meteoroligical Office in Bracknell lost no time in taking up this new invention so enabling its staff to forecast the

weather more accurately Geoff Tootill subsequently left to join Ferranti to add his expertise to eventually produce 

the Ferranti Mark 1

Geoff Tootill Honoured.

On April 4th 2005, Geoff was honoured with the naming of his own Laboratory, the Tootill Teaching Laboratory in the University School of Computer Science. This laboratory will be based in the Kilburn Building and will be used to train engineers in Computer Science.tootill 50 year honour

                                 Geoff Tootill, when contacted was very surprised and said, "to be nominated for a blue plaque is an honour. 

                                  I heard nothing for 50 years and since then things have happened, including the laboratory named after me".


On September 2014, two members of the Chadderton Historical Society on a break in Manchester took the opportunity to examine the 'Baby' experimental computer. We also chatted to the stall minder; and received some very useful information. It turns out that he knew about Geoff Tootill but had little information other that we already knew .
