What is a summary of chapter 1 of Cheaper by the Dozen?

Chapter 1 begins with the narrator informing readers about her father. We are quickly informed that he is an incredibly intelligent and driven man. He brings home his drive for efficiency and employs it with his family of 12 children. For example, he films his kids doing the dishes in order to study how to maximize their effort on that kind of task. He also would make his children initial a chart in the bathroom to help the kids track whether or not they brushed their teeth, took a bath, etc. The narrator goes on to explain that her father is essentially an efficiency expert.
The text moves on to tell readers about a time when the father was left at home to take care of all 12 children. He admitted that he only had a problem with one kid, and it turned out that the child belonged the neighbors next door. The funny thing is that none of the kids actually remember that happening, so nobody actually knows if the dad was joking or not. Apparently, the father is efficient with a sense of humor.

Dad was happiest in a crowd, especially a crowd of kids.

Readers are then told that Mr. Gilbreth most likely had 12 kids because he loves children that much. Of course, the narrator then admits that perhaps her dad just loved having an audience, and 12 kids ensures a constant audience.
The chapter ends with the narrator informing readers of how her father behaviorally conditioned all of the kids to come running to him at the sound of a very specific whistle that he would use.

So when we heard him whistle, we never knew whether to expect good news or bad news, rags or riches. But we did know for sure we'd better get there in a hurry.
