National fraternities that pioneered a campus

[oldu]

In an accompanying thread I listed the number of institutions and the era in which national fraternities were introduced. Here is a list of which fraternities they were.

By 1850 the fraternities with the largest number of chapters which pioneered a campus were:

Alpha Delta Phi, 11
Beta Theta Pi, 9
Delta Kappa Epsilon, 3
DElta Psi, 3
Mystical Seven, 3
Sigma Phi, 3

By the turn of the twentieth century more familiar names appear. In 1900 the fraternities with the most pioneer chapters were:

Beta Theta Pi, 26
Delta Tau Delta, 19
Sigma Alpha Epsilon, 19
Phi Delta Theta, 16
Phi Gamma Delta, 15
Phi Kappa Psi, 15
Alpha Delta Phi, 13
Alpha Tau Omega, 13
Kappa Sigma, 12
Delta Kappa Epsilon, 10
Phi Kappa Sigma, 10
Sigma Nu, 10
Kappa Alpha Order, 9
Sigma Chi, 8
Zeta Psi, 8

Fifty years later some of the younger fraternities became more aggresive at opening news schools to national Greek organizations, while some of the older groups became more conservative. The pioneers by 1950 were:

Sigma Tau Gamma, 29
Beta Theta Pi, 27
Kappa Alpha, 24
Omega Psi Phi, 24
Sigma Alpha Epsilon, 24
Alpha Phi Alpha, 23
Kappa Sigma, 22
Delta Tau Delta, 20
Phi Delta Theta, 19
Sigma Nu, 18
Alpha Tau Omega, 17
Phi Gamma Delta, 15
Phi Kappa Psi, 15
Alpha Delta Phi, 13
Sigma Chi, 13
Phi Beta Sigma, 13
Pi Kappa Alpha, 13
Delta Kappa Epsilon, 10
Phi Kappa Sigma, 10
Zeta Psi, 10

The list today reflects the dramatic expansion of the Greek system during the last half of the twentieth century and the groups most aggressive at adding chapters. It is also interesting that some of the largest groups have tended to wait until a Greek system was well established before placing chapters, while others chose to be first in. As of today, the pioneer chapters are:

Tau Kappa Epsilkon, 93
Kappa Sigma, 51
Sigma Phi Epsilon, 49
Sigma Tau Gamma, 49
Alpha Phi Alpha, 37
Kappa Alpha, 35
Omega Psi Phi, 33
Beta Theta Pi, 31
Phi Delta Theta, 31
Pi Kappa Alpha, 31
Sigma Alpha Epsilon, 31
Delta Sigma Phi, 30
Pi Kappa Phi, 25
Alpha Tau Omega, 24
Delta Tau Delta, 23
Sigma Nu, 22
Alpha Phi Delta, 21
Sigma Chi, 21
Phi Beta Sigma, 20
Phi Kappa Psi, 18
Phi Kappa Sigma, 18
Phi Sigma Kappa, 18
Sigma Pi, 18
Theta Chi, 18
Phi Gamma Delta, 17
