M.L. Khanna has a legacy of inspiring millions of Engineering candidates towards their goal of becoming successful Engineers over the last five decades. He gained most acclaim for his IIT-JEE main exam preparation books, with both his Objective and Subjective guides considered bibles by aspirants across the country for decades. Born in 1928 in Patiala, Madan Lal Khanna worked his way to earn his B. Sc. and M. Sc. in Mathematics from St. John's College, Agra. After beginning his teaching career at the same college, he went on to join Meerut University in 1949. He published his first book on the B. Sc. Mathematics curriculum in 1952 and would eventually go on to publish over 50 books spanning a broad range of Mathematics topics for the Graduate and Postgraduate levels and retiring as the 'Head of Department' of Mathematics at Meerut College in 1986.
Through a career spanning over 50 years, Professor Khanna made his mark not just through his published works but also through a career devoted to teaching. His personal belief in the adage that 'Practice makes perfect' guided him to ensure that math was accessible to all students and not just the ones who felt they were naturally talented. His philanthropic endeavors covered scholarships and academic support for 100s of students who aspired for the IIT and other prestigious engineering universities across the country and he personally continued his teaching endeavors until 2008, through subsidized tuitions conducted in his home premises for close to ~ 250 students annually.
