Father of Accountancy
Founder Mr Kalyan Subramani Aiyar, born 6th June 1859 is regarded as the Father of Accountancy by The Institute of Chartered Accountants of India (ICAI).
Mr K S Aiyar set up the firm in Calicut in 1897 and then moved the Firm to Mumbai (then Bombay).
Mr K S Aiyar was a pioneer in Indian Accountancy and of the Accountancy profession, but an educationist at heart. While the Firm grew under his leadership, he regarded the Firm as a medium to further the cause of commercial education. He was instrumental in procuring permission from the Society of Incorporated Accountants & Auditors UK, for training apprentice’s in India for their London examination.
K S Aiyar spent the evening of life in Bangalore until his end came on 2nd January 1940. Even during his sunset years he gathered many friends and admirers.
