I have heard the name, and am somewhat familiar with who he was, but I am by no means an authority on his life. Why?
If you have heard the name you are ahead of most history professors out there today as the revisionists have done their best to erase his name from the history of the United States.
What did he do? Not much really. In 1803 He published a work entitled
Blackstone's Commentaries:
with Notes of Reference (5 volumes)
http://www.lonang.com/exlibris/tucker/index.html an annotated version of Blackstone's Law which incorporated the United States Constitution. The law books at every school of law in the country for the next 50 years!
So why has his name been largely erased? Because his view of the founding, and the nature of the Republic, did not match that of those beginning to come to power in the mid 1850's. He is definitely not the only example either.
What do I mean when I say HONEST history? I mean history as it happened warts and all! Not the "history is what historians say it is" garbage being passed off on folks currently.
HONEST science is science that is provable and repeatable quite unlike the agenda driven drivel we see so much of these days.
Hope this answers your question.
One more thing before I go. Be VERY careful with honesty in university history departments. The people who populate those places don't value it much and if you want to work there you need to be REALLY careful with it!
