They had a dozen children, six boys and six girls, in seventeen years. One reason Dad had so many children was that he was confident anything he and Mother teamed upon was sure to be a success.

Our house at Montclair, New Jersey, was a sort of school for scientific management and the removal of wasted motions — or “motion study,” as Dad and Mother named it.

Dad took moving pictures of us children washing dishes, so that he could determine how we could reduce our motions and thus hurry through the task. Each child who wanted extra pocket money put forward an offer saying what he would do the job for. The lowest bidder got the contract(合约).

Dad put process and work charts in the bathrooms. Every child old enough to write — and Dad expected his children to start writing at a young age — was required to sign their names on the charts in the morning after he had brushed his teeth, taken a bath, combed his hair, and made his bed. At night, each child had to weigh himself, mark the figure on a graph, and sign the process charts again after he had done his homework, washed his hands and face, and brushed his teeth. Mother wanted to have a place on the charts for saying prayers, but Dad said as far as he was concerned prayers were voluntary.

It was strict management, all right. Yes, at home or on the job, Dad was always the efficiency expert. He buttoned his vest from the bottom up, instead of from the top down, because the bottom-to-top process took him only three seconds, while the top-to-bottom took seven. He even used two shaving brushes to make his face smooth enough, because he found that by so doing he could cut seventeen seconds off his shaving time. For a while he tried shaving with two razors, but he finally gave that up.

“I can save forty-four seconds,” he complained, “but I wasted two minutes this morning putting this bandage on my throat.” It wasn’t the injured throat that really bothered him. It was the two minutes.
