I was saddened as I read the article wondering why the entire time. Why did he try to re-invent the patent? It seems that even the brightest of people can fall prey to the temptation to fudge things a little (I could not tell whether he really did first invent or not, but he did file the patent application). I wonder if it was pride or greed that caused him to make the original bad judgement? Lesson for all us is to not mess with the facts.
This is why integrity and ethics are so important in engineering and business. One step across the line can erase a lifetime of accomplishments.
The good news is that only you can give away your integrity. Nobody can ever take it from you.
