The author of this book is probably not LDS but when I read this question two answers came to my mind at the same time. I had to go to the internet to make sure that my memory was correct and it was but the internet also made it possible for me to add images of each. So here they are.
The President of the United State of America was Dwight D Eisenhower. He was president until I was 8 years old.
The President of the Church of Jesus Christ of Latter-day Saints was David O McKay.
He was president of the church until I was 17.
