The Alter of Slabodka died in 1927. Suppose someone today wanted to learn the unique "Slabodka approach" as embodied and taught by the Alter. Are there any remaining students of the Alter alive today (they would presumably have to be over 100 years old) that one could learn from? If not, are there any second generation students that are known** to represent the Slabodka approach?
(Note, Wikipedia has a partial list of famous students of the Alter who went on to become influential in many of the modern day yeshivos. I am not simply asking for a list of students. My question is specifically if there is someone alive today who is known** to accurately represent the Alter's approach and can give it over to a student.)
** This is obviously somewhat subjective. The closer to objective the better (e.g. the Alter is recorded as saying that So-And-So follows his path).
