A political figure who was a good politician/statesman and had a good behaviour?

I was reading about Sun Yat-Sen, and all his political achievements. The guy was smart, because not many people can end a 2000-year-old government system. But reading through his personal life, well he wasn't the best of husbands, when he was 35 he proposed a 13 year-old girl. I know, a whole different age and social context, but still, he endlessly cheated on his wife.

What's a high-profile political/revolutionary figure you can think of who was a good politician/leader/stateman and also had good personal behaviour?
