Willie Orr arrived at Celtic Park in May 1897 from Preston North End, one of the last big names to come in before Willie Maley began the policy of Celtic rearing its own players.
Willie was an immediate success, playing a solid part in Celtic winning the League title in 1898 and from that point on, was almost an ever-present at left-back or left-half as the club picked up Scottish Cups in 1899, 1900, 1904 and 1907, captaining the club on the latter two occasions. He was also in the side which relieved Rangers of the 1901 Glasgow Exhibition Cup, when Celtic beat the Light Blues 3-2 at Cathkin. And Willie led the team to the championship wins of 1904/05 and 1905/06, before handing over the captaincy to Jim Hay.
After a career lasting just over 10 years, covering 212 appearances and 23 goals, Willie Orr ran out in the Celtic jersey for the final time in an official match on the this day in 1907, when the Bhoys lost 1-2 to Aberdeen.
