Answer:
Muthu Iyer
When Kalam was 5 years old, he had a teacher Muthu Iyer. He took a special interest in Kalam because he performed well in class.
Iyer played a crucial role in nurturing good habits in Kalam. One of those habits was teaching the importance of good handwriting. Iyer noticed that Kalam's handwriting was "very poor". He gave a three-page writing exercise and told Kalam's father that he should ensure that he does the exercise every day regularly.
Step-by-step explanation:
When Kalam was to St. Joseph's College, he came in contact with his Mathematics teacher, professor Thothatri Iyengar.
"When he walked, knowledge radiated all around," Kalam recalled.
He taught the students to take pride in India's contribution to astronomy and mathematics and put the students ahead.
"Professor Thothatri Iyengar was an example of continuously building capacities among students and putting the students well ahead in mathematical sciences. He also injected great thoughts in the minds of students and promoted nobility in thinking and action," Kalam later wrote.
