Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

Babel is required to process package imports. If you need a different preprocessor remove all packages first.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

      <h3><b>Time Line of Dennis M. Ritchie Life </b></h3>
      <ul style="text-align:justify;">
        <li>Dennis M. Ritchie was born in September 9, 1941, Bronxville, Eastchester, New York, U.S. He is an american computer scientist.</li><br>
        <li>Ritchie and the American computer scientist Kenneth L. Thompson were cited jointly for “their development of generic operating systems theory and specifically for the implementation of the UNIX operating system,” which they developed together at Bell Laboratories. </li><br>
<li>In 1963 Ritchie earned a bachelor’s degree in physics and a doctorate (1968) in mathematics from Harvard University.</li><br>
        <li>In 1967 he joined Bell Labs, where he first worked on the Multics operating system (OS).</li><br>    
        <li>Ritchie joined Thompson in developing a more flexible operating system for Bell Lab’s obsolete Digital Equipment Corporation (DEC) PDP-7 minicomputer. Within a few months they had created UNIX, a new OS.</li><br>
        <li>In 1970 Ritchie contributed somewhat to Thompson’s creation of the B programming language.</li><br>
        <li> In 1972 Ritchie extended the B programming language to create the C programming language. C and its family of languages, including C++ and Java, remain among the most widely used computer programming languages.</li><br>
        <li> In 1973 Ritchie and Thompson rewrote UNIX in C.</li><br>
        <li>In 1983 Ritchie was named a fellow by Bell Labs and was elected to the U.S. National Academy of Engineering in 1988.</li><br>
        <li>In 1990 he was appointed head of the System Software Research Department at Bell Labs.</li><br>
        <li> In 1998 Ritchie and Thompson were awarded the U.S. National Medal of Technology for their development of UNIX.</li><br>
        <li>In 2011, dies at the age of 70. </li>

        We're all standing on Dennis' shoulders."</i></b></center></p><br>
