It is difficult to describe in short the enthusiasm and devotion provoked by and given to my research. We lived almost in poverty. I used pencils, two for a nickel, and could not buy a fountain pen, when I lost mine.

I work by hand, with a fountain pen, in bound notebooks I buy in India.

I've always written by hand. Mostly with a fountain pen, but sometimes with a pencil - especially for corrections.

I have to write a first draft with a fountain pen before I type it up as a second.

When I was at school, I used to end every school day with fountain pen ink all over my hands and face and down my shirt.

I write everything with fountain pens. I don't know why. I've done it since I was bar mitzvahed. I was given a fountain pen, a Parker fountain pen, and I loved it, and I've never liked writing anything with pencils or ball-points.
