A search for excited fermions f* of the first generation in e(+)p scatterin
g at the collider HERA is presented using H1 data with an integrated lumino
sity of 37 pb(-1). All electroweak decays of excited fermions, f* --> f gam
ma fW, fZ are considered and all possible final states resulting from the Z
or W hadronic decays or decays into leptons of the first two generations a
re taken into account. No evidence for f* production is found. Mass depende
nt exclusion limits on cross-sections and on the ratio of coupling constant
s to the compositeness scale are derived.
