[00:01.70]A few years later, penicillin 1 was being mass-

[00:04.38]produced and helping 2 to save the lives

[00:06.82]of millions.

[00:08.31]Despite the incredible outcome of his discovery

[00:11.08]Fleming remained modest.

[00:13.06]"Nature makes penicillin," he said,

[00:15.34]" I just found it."

[00:17.57]During the Second World War,

[00:19.26]when penicillin was first being used,

[00:21.48]the US Navy wre looking for ways

[00:23.19]of improving the accuracy of their missiles,

[00:25.98]but this was very complex.

[00:28.17]The navy turned to Eckert,

[00:30.38]an engineer, and Mauchly, a physicist 3,

[00:33.54]to produce a machine to do the job.

[00:36.08]Although they and their team did not finish

[00:38.21]the machine until after the war,

[00:40.42]in February 1946, it did not matter.

[00:43.49]This huge machine

[00:45.35]was the world's first computer.

[00:47.51]But it was nothing like our computers today.

[00:50.27]It measured 100 feet long by over 10 feet high

[00:53.57]and weighed over 30 tonnes.

[00:56.02]And with 18,000 tubes and 6,000 switches,

[00:59.49]it used so much energy

[01:01.14]that when it was turned on,

[01:02.83]the lights in the local town went out!

[01:04.43]
