Shri Prem Bihari Narain Raizada (Saxena) was the calligraphist of the Constitution of India, who hand written (Calligraphed) historic document: the Constitution of free India on the request of Jawahar Lal Nehru (The Prime Minister of India at that time). His only demand was to write his initial (PREM) on each of the pages of the constitution he calligraphed. Nehru gave him a room in the house of Parliament to set up his calligraphy studio. Bundles of parchment sheets were neatly arranged. Over 400 penholders with nib number 303b were kept ready. The nibs were brought from England and Czechoslovakia.
Before Prem Bihari began the work, President Rajendra Prasad took Prem Bihari to Santiniketan to meet artist Nandalal Bose. Prem Bihari discussed with Bose how the pages would be laid out, where the text would appear, and where Bose would place illustrations and decorations to add beauty to the precious book which the nation was eagerly waiting for.
