What were some experiments performed by dr. mengele at auschwitz?

Dr. Mengelee, also known as Josef Mengelee, was a doctor that proformed horrific acts on prisiners (specifically twins) in concentration camps durring WWII.

I'm sorry in advance if I misspell anything.

Explanation:

He would take twin children when they first got to the camp and would give them food and medical attention as needed. But soon after he would begin his expierments.

He would then tortour the twins by using injections and would also continuously measure them and compare their twins mesurments.  

Only 200 out of the 3,000 people that were forced to partake in these expierments survived.
