Albert Einstein is a famous scientist and the analysis of his kundali is very interesting.
Albert Einstien Kundali by Astrovidya famous astrologer Saurin Dave

There is a debilitated planet mercury is a cause of worry in astrology and einstein has debilitated mercury in 10 th house with exaulted venus. This cancels the bad effects of debilitated mercury because of conjuct with exault venus and cause a NEECHBHANG RAJ YOGA. Interesting is the debilitated mercury is a lagna lord which governs the fame and personality as well as the lord of 4 th house which governs knowledge and education degree in his chart.

Mercury in Vedic Astrology rules over communication, intellect, education, teaching, science, philosophy, mathematics. A debilitated Mercury should have deprived Einstein of all these things, but as we know that he considered the greatest scientist of all time.

A debilitated planet also gives its bad effects during its mahadasha. As we all know Einstein had communication problems as a toddler. Mercury rules over communication and till the age of 10, Einstein was under his Mercury mahadasha. Einstein also had to leave his homeland and permanently migrate to the United States of America. In fact the German government had also announced a bounty on his head and he was on a list of most wanted criminals. This trouble from homeland is because Mercury is also the lord of the fourth house, which reflects residence, home, etc.

A debilitated planet thus can give both good and bad effects, depending on its lordship, placement, and the aspects it receives from different planets.
Einstein became famouse scientist because of his NEECHBHANG RAJ YOG  in 10th house.

 There is also a parivartan between 10th house lord jupiter with 9th house lord saturn. This is again a big raj yog which is called dharma karmadhipati yog. Saturn plays important role in scientist and in einsteins chart saturn is also the lord of eighth house.

Also there is no planets on either side of the house from moon, which caused a KEMDRUM YOG. Because of this yog he has to suffer from few family related problems.
