- This led to the development of the indoor Morrison shelter . }}
- The government distributed Anderson shelters until 1941 and that year began distributing the Morrison shelter, which could be used inside homes.
- In 1940 Morrison was appointed the first Minister of Supply by Winston Churchill, but shortly afterwards succeeded Sir Morrison shelter was named after him.
- In July 1950 the Royal Commission on Awards to Inventors made an award of ?, 000 ( ?| r =-3 } } } } ) to Baker for his design of the Morrison shelter . }}
- Half a million Morrison shelters had been distributed by the end of 1941, with a further 100, 000 being added in 1943 to prepare the population for the expected German V-1 flying bomb ( doodlebug ) attacks.
- During the seven-month Phoney War period following the outbreak of war in September 1939, ARP wardens mainly offered advice, issued gas masks and air raid shelters ( such as the external Anderson and internal Morrison shelter ) and enforced the blackout.
- On the first night of the Blitz, 430 civilians were killed and 1, 600 seriously wounded . and digging in, constructing Anderson shelters in their gardens and Morrison shelters in their houses, or going to communal shelters built in local public spaces.
- During the Second World War, the ARP was responsible for the issuing of gas masks, pre-fabricated air-raid shelters ( such as Anderson shelters, as well as Morrison shelters ), the upkeep of local public shelters, and the maintenance of the blackout.
- Prof . Baker's views were developed from his pre-war work on steel structures and further informed by his wartime experiences assessing blast-damaged structures and with the design of the " Morrison Shelter ", an air-raid shelter which could be located indoors.
- In one examination of 44 severely damaged houses it was found that three people had been killed, 13 seriously injured, and 16 slightly injured out of a total of 136 people who had occupied Morrison shelters; thus 120 out of 136 escaped from severely bomb-damaged houses without serious injury.
- By the 1960s it was being taught in the undergraduate engineering course at Cambridge University, and Baker presented an undergraduate lecture on the principles of design of the Morrison shelter as an interesting introduction to his theory of plastic design of structures; in 1968 this lecture was attended by Prince Charles, and it can be summarised as follows:
