As a born Chicagoan and resident for most of my life I did appreciate that for the most part this was accurate. Chicago has had a lot of calamities. I don't think I realized just how many until I was reading this.
Obviously, the major ones were the fire in 1871 and the fire at Our Lady of the Angels in 1958; the snow storm of '67; the great seiche of '54; the Haymarket Square riot of 1886; the sinking of the Eastland in 1903 and the Democratic National Convention of '68 among others.
Everyone loves to point out the two survivors of the Great Fire - the water tower and the similarly built stone building across the street. Many changes came about because of this - most especially the building codes. Although judging from the Iroquois Theater in 1903 shows that the codes were not changed enough or not sufficiently enforced. (My goodness, they must have just been getting over the sinking of the Eastland when the fire broke out at the Iroquois just after Christmas, with many children in attendance.)
I was only 4 at the time of the great seiche and lived in a northwestern suburb and so have no memory of it, although I did experience other seiches throughout my youth and vividly recall being barred from entering Lake Michigan because there was a seiche warning. Other days there would be very strong undertow.
But I did remember the fire at the school. I had recently moved to a northern suburb and this was the first time I remember reading the newspaper. The picture of all the victims spread out in the newspaper is marked indelibly on my brain. The schools in my suburb were not built like the Catholic schools in the city and maybe not even like the public schools in the city. But this school had enclosed staircases which was not a problem in my town. But, still, people were fearful of going back to school and we had to be shown the many ways my school was not like the school that had burned.
The 1967 snow storm was the first time my school ever closed for a snow day! Since then it has closed several times, both for snow and for extreme cold. Admittedly, it has to be at least 27" worth of snow for it to happen. This is partly because in Chicago (and in my suburb) most people live within a couple of blocks of public transportation, which almost always works.
My only complaint about the reporting on the Convention and the related riots was that the author discussed the assassination of Martin Luther King before Lyndon Johnson announced that he would not be running. Only they occurred in reverse order. Johnson made the announcement in March and King was killed in April.
So for the most part this was an all right book. She was a decent writer. I sometimes wondered why she presented the disasters in the order that she did.
