It is believed that pens were first used in India, somewhere in the fifth century BC. Bird feathers or quills were used, as were thin bamboo sticks, cut at the end to make a sharp point. Metal (copper) nibs were developed in the first century, and used to write with by dipping the tip into ink. In the tenth century a fountain pen with a reservoir was developed in Egypt. John Loud patented the fist ball point in 1938. The 1960s brought us felt-tip pens and the 1980s saw roller-ball pens arrived. Please see the related link below for more details.
