Lawson was the son of a farmer and he grew up in Indiana County, Pennsylvania. He was just one of sixteen children. All of his brothers were athletic and largely built, however Lawson was considered the toughest of family.
Football
Princeton
Lawson may have played some informal football at Indiana Normal School in the late 1880s. By 1891, he and Ross played well enough to receive "liberal expense money" to go toPittsburgh and play for the Allegheny Athletic Association. In 1892, Lawson was recruited to play football at Princeton University. At the time, college football was considered more prestigious than professional football. While at Princeton, Fiscus played guard and excelled at the position. However, he dropped out of school and returned home after the 1892 season.
During the first half was of the Jeannete game Fiscus got into an altercation with an unknown Jeannette player. Several accounts of the incident describe Fiscus kicking the Jeannette player in the face. However, the Pittsburgh Press reported that he tripped the guy and "purposely tramped on his neck." Either way Jeannette immediately petitioned the referee to expel Fiscus from the game, while Greensburg defended Fiscus' actions. The arguments continued through to the second half of the game. Finally, either Jeannette or Greensburg stormed off the field in protest and the game was declared a scoreless draw.
1896
In 1896 Lawson and his brother Ross Fiscus manned the halfback slots for Greensburg, while is other brother Newell became the team's offensive tackle. The team accumulated a 5-0-0 at the end of October, and had a final record of 6-1-1. This was Greensburg's best finish since the team began playing football in 1890. In 1897 Fiscus helped Greensburg win the "Western Pennsylvania football championship".
After football
Fiscus continued to play football with Greensburg for the next several years. He was later involved in businesses throughout the years. Still later, he became a police chief in Youngwood, Pennsylvania. For the longest time sports historians were convinced that pro football had begun in 1895 when the Latrobe Athletic Association offered to pay John Brallier $10 to play against Jeannette. However just before his death in 1949, Fiscus announced he was paid $20 by Greensburg a year earlier and believed himself to have been the first pro football player. Today, Fiscus is the sixth player known to have been openly paid to play football. However, after looking at the list of the first several professional football players, Fiscus seemed to be unaware that some of his Allegheny Athletic Association teammates in 1893 had been salaried.
