<script type="text/javascript">
jQuery(function ($) {
    $('input[name="dob1"]').datepicker({
        "dateFormat": "mm/dd/yy",
            "firstDay": "1",
            "changeMonth": true,
            "changeYear": true,
            "yearRange": "1930"
    }).datepicker('option', 'onSelect', function () {
        $(this).removeClass('watermark');
    });

Answer 1

Change your "yearRange": "1930" to "yearRange": "1930:+0"

or if you want it to start at 1930 and go forever set it to "1930:9999"
