The Self-Made Man

David Rittenhouse (1732-1796)  was a world renowned astronomer, scientist, mathematician, surveyor and inventor.

He was also entirely self-taught.

Rittenhouse grew up near Germantown, PA.  It is said that at age 13 he had mastered Newton's laws of motion and gravity.  He was one of the first Americans to build a telescope and used his to observe the transit of Venus across the sun in 1769.

Based on his observations, Rittenhouse stated that the distance between the earth and the sun was 93,000,000 miles.  He was, of course, correct.

He built his home in Philadelphia where he regularly held salons attended by Benjamin Franklin and others.  Thomas Jefferson said "he would rather attend one of those meetings than spend a week in Paris."

Rittenhouse proves that genius is where you find it.  Jefferson's encomium, from a man who had lived in France for years and was revered by European intellectuals, underscored that America could think, too.

Rittenhouses's portraitist, Charles Wilson Peale, studied under John Singleton Copley and Benjamin West.  He was around at the right time.  In Philadelphia in 1776 he painted portraits of Washington, Hancock, Franklin, Hamilton and Jefferson.

Peale fought in the American Revolution, gaining the rank of Captain in the Pennsylvania Militia.

    It sounds very civilized — like the salons in France.  Someone else who was rather like this was Benjamin Banneker, whose bio. my Dad wrote. As you doubtless know, Eric, he surveyed the land this city stands on.  And considering he was a Black man in that day and time his accomplishments were doubly amazing.

    Very interesting you should mention that, Rittenhouse also colloborated with Andrew Ellicott to complete the Mason-Dixon survey.

Delusional? Take a look in the mirror Eric. You have come to conclusions without providing solid facts, all you've been providing is rhetoric and hearsay. You say the union is corrupt, you say delegates have no say, well gues what, there is a process which spells out directly how to address such issues, a process…

M- The simple fact is that Schaitberger runs the MDA as a for-profit IAFF business netting $1.4 million a year when he shakes them down. $1.4 million could help a lot of kids and families. All you will hear from those in positions of authority is silence. They just want you to forget about it.…

Prove it? Dude, it's on the IAFF website. Smell the coffee. refuse to accept the simple fact that IAFF gets a $1.4 million kick-back from MDA. It’s nothing more than a Schaitberger shakedown. $1.4 million could help a lot of kids and families.
